CONTRACT OF PURCHASE

June 21, 2017

City of Chicago
Office of Chief Financial Officer 121 North LaSalle Street, 7th Floor Chicago, Illinois 60602 Attn: Chief Financial Officer
The undersigned, Loop Capital Markets LLC (the "Representative"), acting on behalf of itself and the other underwriters named in the list attached hereto marked Schedule I, on whose behalf the Representative is duly authorized to act (hereinafter, each individually referred to as "Underwriter" and collectively, with the Representative, referred to as "Underwriters"), hereby offers to enter into this Contract of Purchase (the "Contract of Purchase") with the City of Chicago, a municipal corporation and a home rule unit of local government duly organized and existing under the laws of the State of Illinois (the "City") whereby the Underwriters will purchase and the City will sell the 2017 Senior Lien Bonds (as defined and described below). This offer is made subject to the City's acceptance of this Contract of Purchase on or before noon, Chicago time, on June 21, 2017, or such other time as agreed to by the Representative and the City. If the City accepts this Contract of Purchase, this Contract of Purchase shall be in full force and effect in accordance with its terms and shall bind both the City and the Underwriters. The Underwriters may withdraw this Contract of Purchase upon written notice delivered by the Representative to the Chief Financial Officer of the City at any time before the City accepts this Contract of Purchase. Except as otherwise defined herein, capitalized terms used herein shall have the same meanings as defined in the Official Statement (as defined below).
1. Purchase and Sale. Upon the terms and conditions and in reliance upon the representations, warranties and covenants set forth herein, the Underwriters hereby agree to purchase from the City, and the City hereby agrees to sell and deliver to the Underwriters, all (but not less than all) of the City's $812,495,000 aggregate principal amount of (a) Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2017A, Series 2017B and Series 2017C and (b) Chicago O'Hare International Airport General Airport Senior Lien Revenue Bonds, Series 2017D (collectively, the "2017 Senior Lien Bonds"). The 2017 Senior Lien Bonds will be issued in four series:


QB\45789704.6

$55,915,000 aggregate principal amount of Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2017A (Non-AMT) (the "2017A Senior Lien Bonds");
$356,385,000 aggregate principal amount of Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2017B (Non-AMT) (the "2017B Senior Lien Bonds");
$122,120,000 aggregate principal amount of Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2017C (Non-AMT) (the "2017C Senior Lien Bonds"); and
$278,075,000 aggregate principal amount of Chicago O'Hare International Airport General Airport Senior Lien Revenue Bonds, Series 2017D (AMT) (the "2017D Senior Lien Bonds").

The 2017 Senior Lien Bonds shall: (a) be dated as of their date of delivery, (b) have the maturities and shall bear interest at the rates per annum set forth in Exhibit A hereto and (c) have the redemption features and the further terms set forth in Exhibit A and in the Official Statement of the City, dated the date hereof, relating to the 2017 Senior Lien Bonds (such Official Statement, including the cover page and all appendices included therein, is hereinafter called the "Official Statement," except that if the Official Statement shall have been amended with the approval of the Representative between the date hereof and the date upon which the 2017 Senior Lien Bonds are delivered for the Underwriters' account with The Depository Trust Company, New York, New York ("DTC"), the term "Official Statement" shall refer to the Official Statement, as so amended).
The Underwriters agree to purchase all (but not less than all) of the 2017 Senior Lien Bonds if the conditions of Closing (as defined in Section 8 hereof) are satisfied. The aggregate purchase price of the 2017 Senior Lien Bonds of $925,631,483.51 (reflecting a par value of $812,495,000 less an Underwriters' discount of $4,279,609.84 plus a net original issue premium of $117,416,093.35), consists of the purchase price for each Series of 2017 Senior Lien Bonds as set forth in Exhibit B hereto (the "Purchase Price"). The Underwriters have made on or before the date hereof, in accordance with Section 2 hereof, a bona fide public offering of all of the 2017 Senior Lien Bonds at prices not in excess of the respective initial offering prices (or yields not less than the yields) set forth in Exhibit A hereto, it being understood and agreed that after the initial offering the Representative reserves the right, subject to the restrictions set forth in Section 2 hereof, to change such public offering prices (or yields) as the Underwriters deem necessary in connection with the marketing of the 2017 Senior Lien Bonds.
The City acknowledges and agrees that: (i) the primary role of the Underwriters, as underwriters, is to purchase securities for resale to investors, in an arm's length commercial transaction between the City and the Underwriters and the Underwriters have financial and other interests that differ from those of the City; (ii) the Underwriters are acting solely as principals and are not acting as municipal advisors, financial advisors or fiduciaries to the City and have not assumed any advisory or fiduciary responsibility to the City with respect to the transaction contemplated hereby and the discussions, undertakings and procedures leading thereto (irrespective of whether the Underwriters have provided other services or are currently providing other services to the City on other matters); (iii) the only obligations the Underwriters have to the City with respect to the transaction contemplated hereby expressly are set forth in this Contract of Purchase; and (iv) the City has consulted its own financial and/or municipal, legal, accounting, tax and other advisors, as applicable, to the extent it has deemed appropriate.


QB\45789704.6

2. Establishment of Issue Price.
The Representative, on behalf of the Underwriters, agrees to assist the City in establishing the issue price of the Series 2017 Senior Lien Bonds and shall execute and deliver to the City and Co-Bond Counsel (as defined herein) at Closing an "issue price" or similar certificate, together with the supporting pricing wires or equivalent communications, substantially in the form attached hereto as Exhibit C, with such modifications as may be appropriate or necessary, in the reasonable judgment of the Representative, the City and Co-Bond Counsel, to accurately reflect, as applicable, the sale price or prices or the initial offering price or prices to the public of the 2017 Senior Lien Bonds. The Underwriters acknowledge that the City and Co-Bond Counsel will rely on said certificate to establish the yield on the 2017 Senior Lien Bonds and for certain other purposes, and that such reliance is material to the City in entering into this Contract of Purchase in connection with the delivery of the 2017 Senior Lien Bonds.
Except as otherwise set forth in Exhibit A attached hereto, the City will treat the first price at which 10% of each maturity of the 2017 Senior Lien Bonds (the "10% test") is sold to the public as the issue price of that maturity (if different interest rates apply within a maturity, each separate CUSIP number within that maturity will be subject to the 10% test). At or promptly after the execution of this Contract of Purchase, the Representative shall report to the City the price or prices at which the Underwriters have sold to the public each maturity of 2017 Senior Lien Bonds. If at that time the 10% test has not been satisfied as to any maturity of the 2017 Senior Lien Bonds, the Representative agrees to promptly report to the City the prices at which 2017 Senior Lien Bonds of that maturity have been sold by the Underwriters to the public. That reporting obligation shall continue, whether or not the Closing Date (as hereinafter defined) has occurred, until the 10% test has been satisfied as to the 2017 Senior Lien Bonds of that maturity or until all 2017 Senior Lien Bonds of that maturity have been sold to the public.
The Representative confirms that the Underwriters have offered the 2017 Senior Lien Bonds to the public on or before the date of this Contract of Purchase at the offering price or prices (the ' "initial offering price"), or at the corresponding yield or yields, set forth in Exhibit A attached hereto. Exhibit A also sets forth, as of the date of this Contract of Purchase, the maturities, if any, of the 2017 Senior Lien Bonds for which the 10% test has not been satisfied and for which the City and the Representative, on behalf of the Underwriters, agree that the restrictions set forth in the next sentence shall apply, which will allow the City to treat the initial offering price to the public of each such maturity as of the sale date as the issue price of that maturity (the "hold-the-offering-price rule"); such maturities are notated on Exhibit A. So long as the hold-the-offering-price rule remains applicable to any maturity of the 2017 Senior Lien Bonds, the Underwriters will neither offer nor sell unsold 2017 Senior Lien Bonds of that maturity to any person at a price that is higher than the initial offering price to the public during the period starting on the sale date and ending on the earlier of the following:

the close of the fifth (5th) business day after the sale date; or
the date on which the Underwriters have sold at least 10% of that maturity of the 2017 Senior Lien Bonds to the public at a price that is no higher than the initial offering price to the public.
The Representative shall promptly advise the City when the Underwriters have sold 10% of that maturity of the 2017 Senior Lien Bonds to the public at a price that is no higher than the initial offering price to the public, if that occurs prior to the close of the fifth (5th) business day after the sale date.|1010|QB\45789704.6

The City acknowledges that, in making the representation set forth in this subsection, the Representative will rely on (i) the agreement of each Underwriter to comply with the hold-the-offering-price rule, as set forth in the AAU (as hereinafter defined) and the related pricing wires, (ii) in the event a selling group has been created in connection with the initial sale of the 2017 Senior Lien Bonds to the public, the agreement of each dealer who is a member of the selling group to comply with the hold-the-offering-price rule, as set forth in a selling group agreement and the related pricing wires, and (iii) in the event that an Underwriter is a party to a retail distribution agreement that was employed in connection with the initial sale of the 2017 Senior Lien Bonds to the public, the agreement of each broker-dealer that is a party to such agreement to comply with the hold-the-offering-price rule, as set forth in the retail distribution agreement and the related pricing wires. The City further acknowledges that each Underwriter shall be solely liable for its failure to comply with its agreement regarding the hold-the-offering-price rule and that no Underwriter shall be liable for the failure of any other Underwriter, or of any dealer who is a member of a selling group, or of any broker-dealer that is a party to a retail distribution agreement, to comply with its corresponding agreement regarding the hold-the-offering-price rule as applicable to the 2017 Senior Lien Bonds.
The Representative confirms that:

any agreement among underwriters (including the AAU), any selling group agreement and each retail distribution agreement (to which the Representative is a party) relating to the initial sale of the 2017 Senior Lien Bonds to the public, together with the related pricing wires, contains or will contain language obligating each Underwriter, each dealer who is a member of the selling group, and each broker-dealer that is a party to such retail distribution agreement, as applicable, to (A) report the prices at which it sells to the public the unsold 2017 Senior Lien Bonds of each maturity allotted to it until it is notified by the Representative that either the 10% test has been satisfied as to the 2017 Senior Lien Bonds of that maturity or all 2017 Senior Lien Bonds of that maturity have been sold to the public and (B) comply with the hold-the-offering-price rule, if applicable, in each case if and for so long as directed by the Representative and as set forth in the related pricing wires, and
any agreement among underwriters (including the AAU) relating to the initial sale of the 2017 Senior Lien Bonds to the public, together with the related pricing wires, contains or will contain language obligating each Underwriter that is a party to a retail distribution agreement to be employed in connection with the initial sale of the 2017 Senior Lien Bonds to the public to require each broker-dealer that is a party to such retail distribution agreement to (A) report the prices at which it sells to the public the unsold 2017 Senior Lien Bonds of each maturity allotted to it until it is notified by the Representative or the Underwriter that either the 10% test has been satisfied as to the 2017 Senior Lien Bonds of that maturity or all 2017 Senior Lien Bonds of that maturity have been sold to the public and (B) comply with the hold-the-offering-price rule, if applicable, in each case if and for so long as directed by the Representative or the Underwriter and as set forth in the related pricing wires.
The Underwriters acknowledge that sales of any 2017 Senior Lien Bonds to any person that is a related party to an Underwriter shall not constitute sales to the public for purposes of this section. Further, for purposes of this section:

"public" means any person other than an underwriter or a related party,
"underwriter" means (A) any person that agrees pursuant to a written contract with the City (or with the lead underwriter to form an underwriting syndicate) to participate in|1010|QB\45789704.6

the initial sale of the 2017 Senior Lien Bonds to the public and (B) any person that agrees pursuant to a written contract directly or indirectly with a person described in clause (A) to participate in the initial sale of the 2017 Senior Lien Bonds to the public (including a member of a selling group or a party to a retail distribution agreement participating in the initial sale of the 2017 Senior Lien Bonds to the public),
(iii) a purchaser of any of the 2017 Senior Lien Bonds is a "related party" to an
underwriter if the underwriter and the purchaser are subject, directly or indirectly, to (i) at least
50% common ownership of the voting power or the total value of their stock, if both entities
are corporations (including direct ownership by one corporation of another), (ii) more than
50% common ownership of their capital interests or profits interests, if both entities are
partnerships (including direct ownership by one partnership of another), or (iii) more than 50%
common ownership of the value of the outstanding stock of the corporation or the capital
interests or profit interests of the partnership, as applicable, if one entity is a corporation and
the other entity is a partnership (including direct ownership of the applicable stock or interests
by one entity of the other), and
(iv) "sale date" means the date of execution of this Contract of Purchase by all
parties.
Official Statement. The City ratifies and consents to the distribution and use by the Underwriters, prior to the date hereof, of the Preliminary Official Statement of the City dated June 9, 2017 relating to the 2017 Senior Lien Bonds (the "Preliminary Official Statement"). For purposes of Rule 15c2-12 ("Rule 15c2-12") of the Securities and Exchange Commission (the "Commission") under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the Preliminary Official Statement is "deemed final" by the City as of its date. As soon as practicable, but not more than seven (7) business days after the City's acceptance hereof, and in any event not later than two (2) business days before the Closing Date, the City shall deliver, or cause to be delivered, to the Representative six copies of the Official Statement, signed on behalf of the City by an Authorized Officer, and the Official Statement so delivered shall be deemed "final" for purposes of Rule 15c2-12. The Official Statement shall be in substantially the same form as the Preliminary Official Statement and, other than information previously permitted to have been omitted by Rule 15c2-12, the City shall only make such other additions, deletions and revisions in the Official Statement which are approved by the Representative. The City hereby agrees to deliver to the Underwriters an electronic copy of the Official Statement in a form that permits the Underwriters to satisfy their obligations under the rules and regulations of the Municipal Securities Rulemaking Board (the "MSRB") and the Commission. The City shall provide, or cause to be provided, at its expense, to the Underwriters as soon as practicable, but not more than seven (7) business days after the City's acceptance of this Contract of Purchase and in time which, in the Representative's opinion, is sufficient to accompany any confirmation that requests payment from any customer, copies of the Official Statement in such quantity which, in the Representative's opinion, is sufficient to comply with the rules of the Commission and the MSRB with respect to the distribution of the Official Statement. The City authorizes the Underwriters to use and distribute the Official Statement in connection with the public offering and sale of the 2017 Senior Lien Bonds. To the extent required by applicable law, the City hereby authorizes the Representative, and the Representative hereby agrees, to file a copy of the Official Statement with the MSRB.

The Senior Lien Master Indenture as supplemented by the Supplemental Indentures and as it may be amended and supplemented from time to time in accordance with its terms, is collectively herein referred to as the "Senior Lien Indenture." The Series 2017 Senior Lien Bonds are being issued primarily to refund certain Refunded Bonds (the "Refunded Bonds") and to pay the costs of the 2017 Airport Projects, as described in the Official Statement and the respective Supplemental Indentures.

As set forth in the Contract of Purchase, Loop Capital Markets and the other members of the Underwriting Group agreed in writing that, (i) for each of the 2033 and 2037 Maturities of the Scries 2017A Bonds, they would neither offer nor sell any of the Series 2017A Bonds of such Maturity to any person at a price that is higher than the Initial Offering Price for such Maturity during the Holding Period for such Maturity (the "hold-the-price rule"), and (ii) any selling group agreement would contain the agreement of each dealer who is a member of the selling group, and any retail distribution agreement would contain the agreement of each broker-dealer who is a party to the retail distribution agreement, to comply with the hold-the-offering-price rule.

IV. Credit
The Common Debt Service Reserve Sub-Fund created or maintained in connection with the Series 20I7A Bonds, Series 2017C Bonds and Series 2017D Bonds is of the size and type that is customarily required in financings of the size and nature of the Series 2017A Bonds, Series 2017C Bonds and Series 2017D Bonds. Such a requirement provides the holders of the Series 2017A Bonds, Series 2017C Bonds and Series 2017D Bonds some measure of protection and work-out time should the City encounter financial difficulties. The failure to provide for this fund at its current size would materially adversely affect the interest rates or Yields at which the Series 2017A Bonds, Series 2017C Bonds and Series 2017D Bonds could be sold.

We enclose copies of the Approving Opinions, dated the date hereof, as to the validity of the Bonds and the exclusion of interest on the Bonds from the gross income of the owners thereof for federal income tax purposes. The Underwriters are entitled to rely on the Approving Opinions as though the Approving Opinions were addressed to them, subject to the following matters, which by acceptance of this letter and the accompanying Approving Opinions the Underwriters recognize and acknowledge: (1) that we have not been engaged to act, and have not acted, as the Underwriters' counsel for any purpose in connection with the issuance of the Bonds; (2) that no attorney-client relationship exists or has at any time existed between our firm and the Underwriters by virtue of the delivery of the Approving Opinions or this opinion; and (3) that the Approving Opinions are based upon our review of proceedings and other documents undertaken as part of our engagement as bond counsel to the City, and in order to deliver this opinion we neither undertook any duties or responsibilities to the Underwriters nor conducted any activities in addition to those undertaken or conducted for the benefit of, and requested by, the City. Consequently, we make no representation that our review has been adequate for the Underwriters' purposes.

This opinion is furnished by us as Bond Counsel to the City. This opinion is solely for the benefit of the Underwriters and the City and may not be used, quoted, relied upon or otherwise referred to for any other purpose or by any other person (including any person purchasing any of the Bonds from the Underwriters) without our prior written consent.

REPORT" OF THE AIRPORT CONSULTANT

The Letter of the Airport Consultant dated June 9, 2017 (the "Airport Consultant's Letter") prepared by Ricondo & Associates, Inc., the City's airport consultant (the "Airport Consultant"), updates certain information previously prepared by the Airport Consultant as part of its November 18, 2016 report incorporated in the Airport Consultant's Letter (such report and the Airport Consultant's Letter are collectively referred to herein as the "Report of the Airport Consultant"). The Report of the Airport Consultant is attached hereto as APPENDIX E. The Report of the Airport Consultant is described more fully under the caption "AIRPORT CONSULTANT" herein. The Report of the Airport Consultant provides certain information with respect to O'Hare and the Capital Programs, evaluates aviation activity at O'Hare and presents the analysis undertaken by the Airport Consultant to demonstrate the ability of the City to comply with the requirements of the Senior Lien Indenture on a pro forma basis for Fiscal Years 2017 through 2025 based on the assumptions set forth therein (the "Projections"). The final maturity date of each Series of the 2017 Senior Lien Bonds extends beyond the period of the Projections. Projections contained in the Report of the Airport Consultant are based on assumptions set forth therein.

As noted below under "-Regarding Use of the Official Statement—Forward-Looking Statements," any projection, including, but not limited to those contained in the Report of the Airport Consultant, is subject to uncertainties, including the possibility that some of the assumptions used to develop the projections will not be realized and that unanticipated events and circumstances will occur. Accordingly, there arc likely to be differences between projections and actual results, which differences could be material. See APPENDIX E - "REPORT OF THE AIRPORT CONSULTANT."
Regarding Use of the Official Statement
Forward-Looking Statements. All statements other than statements of historical facts included in this Official Statement are forward-looking statements, including, without limitation: (a) statements concerning projections of future passenger activity at O'Hare and of future financial performance at O'Hare (see APPENDIX E - "REPORT OF THE AIRPORT CONSULTANT "), (b) statements of the plans and objectives of the :City in relation to the Capital Programs (sec "CHICAGO O'HARE INTERNATIONAL AIRPORT," "AIR TRAFFIC ACTIVITY AT O'HARE" and "CAPITAL PROGRAMS"); and (c) assumptions relating to the statements described in clauses (a) and (b) above (collectively, the "Forward-Looking Statements"). See "CERTAIN INVESTMENT CONSIDERATIONS-Forward Looking Statements."
Projections. The Projections set forth in the Report of the Airport Consultant or otherwise in this Official Statement were not prepared with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information, but, in the view of the City's management, were prepared on a reasonable basis, reflect the best currently available estimates and judgments, and present, to the best of management's knowledge and belief, the expected course of action and the expected future financial performance of the City. However, this information is not fact and should not be relied upon as being necessarily indicative of future results, and readers of this Official Statement arc cautioned not to place undue reliance on the prospective financial information. Neither the City's independent auditors, nor any other independent accountants, have compiled, examined, or performed any procedures with respect to the prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability. Such parties assume no responsibility for, and disclaim any association with, the prospective financial information.
The City has included the Report of the Airport Consultant based upon the Airport Consultant's expertise in the aviation industry. The Airport Consultant believes that the expectations reflected in the Forward-Looking Statements are reasonable. However, there can be no assurance that the expectations contained in the Forward-Looking Statements, including those set forth in the Report of the Airport

|1010|
Consultant, will be achieved. Important factors that could cause actual results to differ materially from the current expectations of the Airport Consultant are discussed in this Official Statement.

The 2017 Senior Lien Bonds are not payable in any manner from revenues raised by taxation. No property of the City (including property located at O'Hare) is pledged as security for the 2017 Senior Lien Bonds.
As described below, the claim of the holders of the Senior Lien Obligations, including holders of the 2017 Senior Lien Bonds, to Revenues of O'Hare is a first lien on and pledge of such Revenues and is|10 10|
senior to the claim of any Junior Lien Obligations. The 2017 Senior Lien Bonds are secured on a parity basis with the City's Outstanding Senior Lien Obligations. Subject to certain conditions set forth in the Senior Lien indenture, the City may issue additional Senior Lien Bonds (the "Additional Senior Lien Bonds") or incur other Senior Lien Obligations that will be secured on a parity basis with the 2017 Senior Lien Bonds and the City's other Senior Lien Obligations.

Description of Revenues
General. "Revenues" consist of all amounts received or receivable, directly or indirectly, by the City for the use and operation of, or with respect to, O'Hare (excluding the Land Support Area); provided, however, Revenues does not include: (i) interest accruing on, and any profit from the investment of, moneys in any fund or account of O'Hare that is not available by agreement or otherwise for deposit into the Revenue Fund; (ii) Government Grants-in-Aid; (iii) the proceeds of any PFC, CFC or similar tax or charge levied by or on behalf of the City including but not limited to, any cargo activity charge or security charge; (iv) insurance proceeds, except to the extent such moneys are deemed revenues in accordance with generally accepted accounting principles, and condemnation award proceeds; (v) amounts derived by the City from Special Facility Financing Arrangements, but only to the extent such moneys are required to pay the principal of, premium, if any, and interest on Special Facility Revenue Bonds and other payments required by Special Facility Financing Arrangements; (vi) the proceeds of any borrowing by the City; (vii) the proceeds of any tax levied by or on behalf of the City; (viii) security deposits and the proceeds of the sale of any O'Hare properly; and (ix) unless otherwise provided in a Supplemental Indenture, any Released Revenues.

"Released Revenues" means any Revenues in respect of which the Trustee has received the following: (i) a request from the City to exclude such Revenues from the pledge and lien of the Senior Lien Indenture; (ii) a Certificate of an Independent Airport Consultant, based upon reasonable assumptions, to the effect that Revenues, after Revenues covered by such request are excluded for each of the five full Fiscal Years following the Fiscal Year in which such certificate is delivered, will be sufficient to enable the City to satisfy the debt service coverage covenant described in the first paragraph under the subcaption "-Debt Service Coverage Covenants" below in each of those five Fiscal Years; (iii) an opinion of counsel to the effect that (a) the conditions to the release of such Revenues have been met, and (b) the exclusion of such Revenues from the pledge and lien-of the Senior Lien Indenture'will not, in and of itself, cause the interest on any outstanding Senior Lien Obligations to be included in gross income for purposes of federal income taxation; and (iv) written confirmation from each of the Rating Agencies to the effect that the exclusion of such Revenues from the pledge and lien of the Senior Lien Indenture will not cause a withdrawal or reduction in any unenhanced rating then assigned' to any Senior Lien Obligations.

Fora complete definition of Revenues, see APPENDIX A - "GLOSSARY OF TERMS." For a general description of the; application of Revenues under the Senior Lien Indenture, see "-Flow of Funds" below and APPENDIX B - "SUMMARY OF CERTAIN PROVISIONS OF THE SENIOR LIEN INDENTURE-Source.of Payment; Pledge of Senior Lien Revenues and Other Moneys."

The Senior Lien Indenture creates the Revenue Fund to be held and administered by the Trustee as provided in the Senior Lien Indenture. The Senior Lien Indenture requires that all Revenues shall be collected by the City and promptly deposited to the credit of the Revenue Fund.

Certain Aviation Fuel Taxes Excluded from Revenues. Pursuant to the Airport and Airway Safety and Capacity Expansion Act of 1987 (P.L. No. 100-223) (the "1987 Airport Act"), aviation fuel taxes imposed at airports which have received federal grant funds must generally bc used for airport capital and operating costs or for a state aviation program or for noise mitigation- purposes' on or Off the airport. However, certain provisions of the 1987 Airport Act authorize the City to use aviation fuel tax revenues generated from aviation fuel taxes at the per gallon rate in effect at O'Hare on December 30, 1987, for other than such permitted airport-related purposes (such provisions of the 1987 Airport Act are referenced in the "Revenue Use Policy" related to such act as "grandfathered"). Such portion of aviation fuel tax revenues do not constitute Revenues pledged to secure the Senior Lien Bonds under the Senior Lien Indenture, and no pledged Revenues are covered by this 1987 Airport Act provision.


11

O'Hare Revenues Must Be Used For Airport Purposes
The Senior Lien indenture provides that moneys and securities held by the City in the Airport Development Fund and, from and after the first Business Day of the Trustee in the month of June, 2018 unless, prior to May 1, 2018, the City files with the Trustee a Certificate electing to select another date as the Transition Date in which case the Transition Date shall be the date selected by the City in a Certificate filed with the Trustee not less than 30 days prior to the date selected by the City (the "Transition Date"), the Airport Genera!

If on any. valuation, date ,under the Senior.Lien Indenture the .amount on deposit in the Common Debt Service Reserve Sub-Fund is more than the. Reserve, Requirement, unless


24

otherwise directed by a Certificate of the City to be withdrawn and deposited in trust to pay or provide for the payment of Senior Lien Obligations, the amount of such excess shall be transferred to the Trustee for deposit into the Revenue Fund, provided, however, that immediately after such withdrawal, the amount on deposit in the Common Debt Service Reserve Sub-Fund equals or exceeds the Reserve Requirement.

If at any time the Common Debt Service Reserve Sub-Fund holds both Qualified Credit Instruments and Qualified Investments, the Qualified Investments shall be liquidated and the proceeds applied for the purposes for which Common Debt Service Reserve Sub-Fund moneys may be applied under the Senior Lien Indenture prior to any draw being made on the Qualified Credit Instrument. If the Common Debt Service Reserve Sub-Fund holds Qualified Credit Instruments issued by more than one issuer, draws shall be made under such credit instruments on a pro rata basis to the extent of available funds.

Deficiencies in the Common Debt Service Reserve Sub-Fund are required to be satisfied from Revenues. Amounts deposited in the Common Debt Service Reserve Sub-Fund shall be applied first to reimburse the Qualified Credit Provider and thereby reinstate the Qualified Credit Instrument and next to make deposits into the Common Debt Service Reserve Sub-Fund. The Common Debt Service Reserve Sub-Fund will be applicable only to the Common Reserve Bonds and will not be available to pay debt service on any other Senior Lien Obligations. See "Payment of Debt Service on the 2017 Senior Lien Bonds" above and APPENDIX B - "SUMMARY OF CERTAIN PROVISIONS OF THE SENIOR LIEN INDENTURE-lndcnture Funds and Payment of Debt Service."

The 2017A Senior Lien Bonds, the 2017C Senior Lien Bonds and the 2017D Senior Lien Bonds are Common Reserve Bonds. Prior to issuance of the 2017A Senior Lien Bonds, the 2017C Senior Lien Bonds and the 2017D Senior Lien Bonds, the Reserve Requirement for the Common Reserve Bonds was $472,346,857.82. Upon issuance of the 2017D Senior 'Lien Bonds, the City intends to deposit $7,043,169.24 of proceeds from the sale of the 2017D Senior Lien Bonds into the Common Debt Service Reserve Sub-Fund which, together with other funds on deposit in the Common Debt Service Reserve Sub-Fund; will increase the amount on deposit to $483,264,562^54, which amount is equal to the new Reserve Requirement for the Common Reserve Bonds, and such sub-fund will be fully funded with cash and Qualified Investments on deposit in satisfaction of the requirements of the Senior Lien Indenture. In addition to the cash and Qualified Investments on deposit, various Qualified Credit Instruments remain on deposit in the Common Debt Service Reserve Sub-Fund. As a result of the widespread losses in the mortgage market and overall credit market challenges, among others, Qualified Credit Providers may experience claims and/or reductions in capital such that their capital resources may no longer be sufficient at their respective rating levels to meet their ongoing additional capital needs and/or to respond to claims, including claims under the Qualified Credit Instruments. In the event of the financial distress of any Qualified Credit Provider that has provided a Qualified Credit Instrument on deposit in the Common Debt Service Reserve Sub-Fund, the City is under no obligation to replace the applicable Qualified Credit Instrument with cash or another Qualified Credit Instrument so long as the Common Debt Service Reserve Sub-Fund remains fully funded with cash and Qualified Investments on deposit in satisfaction of the requirements of the Senior Lien Indenture. Except as may be required by the Undertaking described below under "SECONDARY MARKET DISCLOSURE," neither the City nor the Underwriters undertakes responsibility to bring to the attention of the owners of the 2017 Senior Lien Bonds any information regarding the financial condition of any Qualified Credit Provider or to take any action in connection therewith.

2017B Senior Lien Debt Service Reserve Account. In the Sixtieth Supplemental Indenture, the City covenants that the City will maintain the 2017B Senior Lien Debt Service Reserve Account in an amount equal to the Reserve Requirement for the 2017B Senior Lien Bonds, which requirement may be satisfied with (i) one or more Qualified Reserve Account Credit Instruments, (ii) Qualified Investments, or (iii) a combination thereof. Upon issuance of the 2017B Senior Lien Bonds, the City intends to deposit into the 2017B Senior Lien Debt Service Reserve Account a portion of the proceeds from the sale of the 2017B

Senior Lien Bonds. The Reserve Requirement for the 2017B Senior Lien Bonds is equal to the lesser of (i) $40,223,500.70 or (ii) the maximum amount of principal of and interest on the 2017B Senior Lien Bonds payable in the current or any future Bond Year, and will be fully funded with cash and Qualified Investments on deposit in satisfaction of the requirements of Sixtieth Supplemental Indenture.

Within 60 days following its receipt of the recommendations, the City must revise O'Hare rentals, fees and charges or alter its methods of operation, which revisions or alterations need not comply with the recommendations so long as any revisions or alterations are projected by the City to result in compliance with the required debt service coverage, as described above.

Thus, while it is not possible to predict whether any airline will be contractually obligated to make payments, including, among other things, for debt service on the 2017 Senior Lien Bonds, the Outstanding Senior Lien Bonds or any other Senior Lien Obligations after the expiration date of the Aiqxirt Use Agreements in 2018, the City is obligated under the Senior Lien Indenture to impose fees and charges on the airlines for use of O'Hare that will enable the City lo satisfy the Senior Lien Indenture debt service coverage covenants.

Nonpayment of Rentals, Fees and Charges. The Airport Use Agreements provide that if an Airline Party defaults on the payment of its rentals, fees or charges, and if the City has undertaken appropriate collection efforts and has exhausted certain other specific funds available under the Airport Use Agreements to pay the unpaid rentals, fees or charges, the City then is entitled to include the unpaid rentals, fees or charges in the landing fees payable by the other non-defaulting Airline Parlies. See APPENDIX C - "SUMMARY OF CERTAIN PROVISIONS OF THE AIRPORT USE AGREEMENTS."

Proposed Amendment to the Senior Lien Indenture
The City has proposed an amendment (the "2010 Amendment") to the Senior Lien Indenture that would'remove the restrictions described under "Restrictions on Sales or Transfer of Airport" in APPENDIX B. The 2010 Amendment will not take effect unless and until (among other things) the 2010 Amendment is consented to by the Owners of more than 50% in principal amount of the then Outstanding Senior Lien Obligations and the City determines to present such amendment to the Trustee. Pursuant to the 2017 Supplemental Indentures authorizing each Series of the 2017 Senior Lien Bonds, the Owners of the 2017 Senior Lien Bonds shall be deemed to have consented to the 2010 Amendment by purchasing such 2017 Senior Lien Bonds. Such consent of any Owner may be revoked in writing as provided in the Senior Lien-Indenture. Currently and continuing after the issuance of the 2017 Senior Lien Bonds, Owners of the required percentage of the Outstanding Senior Lien Obligations have consented to the 2010 Amendment and the City thus may elect to implement the 2010 Amendment by presenting it to the Trustee for execution.

REMEDIES

There is no provision for the acceleration of the maturity of the 2017 Senior Lien Bonds if any default occurs in the performance of any other obligation of the City under the Senior Lien Indenture, or if interest on the 2017 Senior Lien Bonds becomes includible, in the gross income of the Owners thereof for federal income tax purposes.

SOURCK: City ofChicago, Department of Aviation Management Records, June 1,2017.

Enplaned passenger traffic at O'Hare can be divided into two primary components: O&D and connecting. O&D enplaned passengers consist of two groups. The first group includes those travelers whose residence and/or place of employment are in the Chicago Region and surrounding communities and whose air trips originate at O'Hare. The second group includes travelers who are not residents of or employed within the Chicago Region and surrounding communities, but who visit for business, personal or pleasure-related activity. Connecting passengers include those passengers traveling from a destination outside the Chicago Region to a destination outside the Chicago Region, who board one aircraft at O'Hare after having arrived on another aircraft at O'Hare. The number of connecting enplaned passengers at O'Hare reflects airline operating decisions, which are in part dictated by the size of the local air passenger market, the profitability of O'Hare to the airlines, and the geographic location of O'Hare relative to heavily traveled air routes.
The following table shows total enplaned passengers, total originating enplaned passengers and total connecting enplaned passengers at O'Hare for a 10-year period from 2007 through 2016. As shown, O'Hare has a strong O&D market with the percent of originating passengers ranging from 47.8% to 54.0% of total enplaned passengers over the 10-year period.

Aircran Operations
The table on the following page shows total aircraft operations at O'Hare for the 10-ycar period 2007 through 2016. From 2007 through 2009, the number of aircraft operations steadily decreased, to 827,899. After increasing to 882,617 in 2010, the number of aircraft operations decreased slightly lo 878,108 in 2012, and increased to 883,287 in 2013 with a slight decrease to 881,933 in 2014. Prior to 2015, United and American shifted domestic passenger service from their mainline service to their regional affiliates, shown by the increase in regional affiliates over the period. Mainline aircraft operations increased from 267,044 in 2014 to 306,670 in 2015. The national economic recession and the recent trend of increasing operating capacity with larger aircraft were the primary cause of total operations at O'Hare decreasing from 926,973 in 2007 to 867,635 in 2016.

(l) Pension Expense is included in 2015 as a separate category due to implementation of Governmental Accounting Standards Board Statement No. 68, Accounting and Financial Reporting for Pensions - An Amendment of GASB Statement No. 27 ("GASB 68"). GASB 68 requires inclusion of certain expenses that are not payable in that year but required to be recorded in the City's Airport financial statements. Prior to GASB 68 (from 2011 through 2014 in the above table). Salaries and Wages included the Pension Expense due and payable in each year.

Discussion of Financial Operations
The "Historical Operating Results" table above summarizes O'Hare's audited financial results for the years 2011 through 2015. Operating revenues in the table are comprised of landing fees, terminal area rental/use charges, other rentals/fueling system fees and concessions. Operation and Maintenance Expenses are comprised of salaries and wages, repairs and maintenance, energy, materials and supplies, engineering and other professional services and other operating costs which include insurance premiums, equipment rentals, vehicles and various miscellaneous costs.



47

The City charges the Airline Parties based on a projection of, and recognizes revenues from the Airline Parties only to the extent required to fund, the net airline requirement (equal to Operation and Maintenance Expenses, net debt service requirements and fund deposit requirements less non-airline revenues and credits). Accordingly, landing fees and terminal area rental/use charges increased S3.6 million in 2015 compared to 2014, due to an increased net airline requirement, driven by an increase in Operation and Maintenance Expenses before depreciation and amortization and an increase in net debt service requirements, which were not completely offset by increased non-airline revenues.
The increase in total'Operation and Maintenance Expenses before depreciation and amortization of approximately $310 million from 2014 to 2015 was primarily due to increases in pension cost resulting from the implementation of GASB 68 and increases in salaries and wages.
'- • of the' $3-39.5 million 'of Pension-Expense recorded for 2015, $25.8 million is the portion of the City's pension contribution payable in 201.5 to the Retirement Funds (as herein defined) and allocable'to O'Hare. The remaining portion of the Pension Expense for 2015 ($313.7 million) is recognized oft the income statement of O'Hare for 2015 pursuant to GASB 68 but is not due and payable by the City during 2015; accordingly, that portion is not included in Operating Expenses for purposes of calculation'of the debt service coverage ratios.

'-'•'¦ ' The increase in non-airline revenue's-and reimbursements of $3 million from 201*4'to 2015 was
primarily due to increases in auto parking, restaurants and auto rentals of $3.9 million, $1.3 million, and
$1.3 million, respectively. ' - '

Determination of Pension Contributions ;;'¦'¦''
Each O'Hare employee participates in one of four single-employer defincd-benefit pension plans for City employees: the Municipal Employees' Annuity and Benefit Fund of Chicago (the "MEABF"),

48

the Laborers' and Retirement Board Employees' Annuity and Benefit Fund of Chicago (the "LABF," and together with the MEABF, the "Municipal and Laborers' Funds1'), the Policemen's Annuity and Benefit Fund (the "PABF"), or the Firemen's Annuity and Benefit Fund (the "FABF," and together with the PABF, the "Public Safety Funds," which, together with the Municipal and Laborer's Fund, arc referred to herein as the "Retirement Funds"). For additional information on the O'Hare's portion of the net pension liability to the Retirement Funds, sec Appendix D - "AUDITED FINANCIAL STATEMENTS-NOTES 7 and 8." The Report of the Airport Consultant in Appendix E sets forth projected Personnel Expenses which incorporates O'Hare's projected contributions to the Retirement Funds from 2016 through 2025.
Members of each Retirement Fund arc eligible (individually, an "Eligible Member," and collectively, "Eligible Members") for an annual annuity payment (the "Annuity Benefits") if they meet certain age, years of service and prior service credit requirements (the "Eligibility Factors"). Benefits to each Eligible Member are statutorily established based on a combination of the Eligibility Factors and the Eligible Member's average annual salary for certain years prior to retirement (the "Annuity Factors").
Annuity Benefits for each of the Retirement Funds are funded from three sources: (i) contributions from the City (the "City Contributions") which are funded from the proceeds of a property tax levy on all taxable property located within the City or other available funds, including payments from O'Hare on behalf of the O'Hare employees, (ii) contributions from Eligible Members (the "Employee Contributions," and together with the City Contributions, the "Contributions"), and (iii) investment returns. O'Hare has historically contributed its pro rata share of City Contributions to the Retirement Systems (the;''O'Hare Portion") based on the Annuity Factors for the number of O'Hare employees who are Eligible Members.
¦ The City Contributions and Employee Contributions are each established by the Illinois Pension
Code (the ""Pension Code"). Except as described under'"-Public Safety Funds," the Contributions
required under thc Pension Code do not relate to, and in recent years have been substantially less than, the
contribution-amounts- that would have been required if the Retirement Funds were funded based on
actuarial determinations of the contribution amounts necessary to fully fund the Annuity Benefits to
Eligible Members of each Retirement Fund over an extended period.-See "CERTAIN INVESTMENT
CONSIDERATIONS - Financial Condition of the City and Other Overlapping Governmental
Bodies" herein. In an effort to improve the funded status of the Public Safely Funds, the Illinois General
Assembly passed Public Act 96-1495 ("Act 1495"), which modified provisions of the Pension Code with
respect to PABF and FABF.|99|' ¦
The City's Fiscal Year 2017 budget includes the following contributions to the Retirement Funds (as indicated by total annual contribution and O'Hare proportional share): (i) $267 million for MEABF, of which $18 million, or less than 7 percent, is O'Hare's proportional share; (ii) $36 million for LABF, of which $2,275 million, or 6.4 percent, is O'Hare's proportional share; and (iii) $727 million for FABF and PABF, of which $18.3 million, or 2.5 percent, is O'Hare's proportional share.

Public Safety Funds
The Pension Code establishes the Employee Contributions to PABF at 9.0 percent of the salary of each employee on an annual basis and Employee Contributions to FABF at 9.125 percent of the salary of each employee on an annual basis and establishes Annuity Benefits for Eligible Members of the Public Safety Funds hired prior to January 1, 2011 based on the Annuity Factors, subject to 3.0 percent automatic annual increases after each member's first full year of retirement. Prior to the effectiveness of Act 1495, the Pension Code established the City Contribution to PABF at an amount based upon a fixed


49

multiplier of 2.00 times the annual employee contributions to PABF and the City Contribution to FABF at an amount based upon a fixed multiplier of 2.26 times the employee contributions to FABF.
Act 1495 provided for the City to contribute the actuarially determined amounts necessary to achieve a 90 percent funded ratio in the Public Safety Funds by 2040, but made no changes to the Annuity Benefits for Eligible Employees hired before January 1, 2011 and established Annuity Benefits for Eligible Members hired on or after January 1. 20i 1 based on the Annuity Factors, but with the average annual salary capped at a certain amount, and the annual increases to the Annuity Benefits tied lo the lesser of 3.0 percent or the consumer price index. Additionally, Act 1495 reduced a survivor's Annuity Benefit equal to 2/3 of the Annuity Benefits that the deceased Eligible Member was receiving at the time of his or her death for Eligible Members hired on or after January 1, 2011.
Beginning with the contribution to be made to the Retirement Funds, in 2016, the City's contributions to PABF1 and FABF will be determined pursuant to P.A. 99-506 ("Act 506") (which modified the funding approach for unfunded,liabilities set forth in Act 1495), rather than the multiplier funding formula. Act 506 (i) extends the period by which the unfunded liabilities of the Public Safety Funds arc amortized, on a level percentage of payroll basis, to a 90 percent funded ratio from 2040 to 2055 and (ii) institutes a phase-in period during 2016-2020 to allow for a more gradual increase in the City Contributions to the Public Safety Funds than originally required by Act 1495.
Municipal and Laborer's Funds.
The current Pension Code establishes Annuity Benefits for Eligible Members of the Municipal
and Laborers' Funds hired prior to January 1, 2011 based on the Annuity Factors, subject to 3.0 percent
automatic annual increases after the members' first full year of retirement and Annuity Benefits for
Eligible Members hired on or after January I, 2011 based on the Annuity Factors, but with the average
annual salary capped at a certain amount, and the annual increases to the Annuity Benefits are tied to the
consumer price index. Further, the Pension Code establishes the Employee Contribution at 8.5 percent of
the salary of each employee on an annual basis and the :City Contribution is established at an amount
based on a fixed multiplier of 1.25 times the annual employee contributions for the MEABF and 1.00 for
thc: LABF. i Without significantly higher contributions or investment returns, the MEABF and LABF are
currently estimated to become insolvent in 2025 and 2027_,_respcctivjeLy„ . : :—

On May 23, 2016, the .City, announced an agreement in principle with unions for employees participating in LABF (the "LABF Plan") pursuant to which the City would begin contributing to LABF on an actuarial basis and certain employees participating in LABF would contribute an increased percentage of their salaries to LABF. Similarly, on August 3, 2016, the City announced an agreement in principle with unions for employees participating in MEABF (the "MEABF Plan" and, together with the LABF Plan, the "Stabilization Plans") pursuant to which the City would begin contributing to MEABF on an actuarial basis and certain; employees participating in MEABF would contribute an increased percentage of their salaries to MEABF.
Pursuant to the Stabilization Plans, Eligible Members of (he Municipal and Laborers' Funds hired on or after January 1, 2017 ("New Members") would contribute an additional 3.0 percent of their salaries to their respective Retirement Funds and would be eligible: for benefits at age 65 (as opposed to age 67 for Eligible Members hired between January 1, 2011 ,and January 1, 2017 ("Tier II Members")). In addition, Tier II Members of the Municipal: and Laborers' Funds would be eligible to receive benefits at age 65 . provided that such Tier IIMcmbers agree to contribute an additional 3.0 percent of their salaries to their respective Retirement Funds.



50

The Stabilization Plans further provide for the City to contribute the actuarially determined amounts required to achieve a 90 percent funded ratio in the Municipal and Laborers' Funds by 2057, following a phase-in of certain increased City Contributions ending in 2022.
The implementation of the provisions of the Stabilization Plans requires amendments to the Pension Code, which require action by the Illinois General Assembly. Senate Bill 2437 ("SB 2437"), introduced in the 99lh General Assembly, contained provisions implementing the MEABF Plan and the LABF Plan and was passed by the Illinois General Assembly, but was vetoed by the Governor. The expiration of the 99lh General Assembly prevented a vote to override the Governor's veto. In January 2017, Senate Bill 0014 ("SB 0014") was introduced in the 100lh General Assembly and contains the same provisions as SB 2437. SB 0014 was approved by the Illinois Senate in January and the Illinois House in April; the Governor has not yet taken any action regarding SB 0014. The City makes no prediction as to whether any such amendments will become law. The City intends to continue to make City Contributions to the Municipal and Laborers' Funds in accordance with the Pension Code in effect when such City Contributions are payable.

Issuance of Additional Airport Obligations. Subject to certain conditions sel forth in the Senior Lien Indenture, the City may issue Additional Senior Lien Bonds or incur other Senior Lien Obligations that will be secured on a parity basis with the 2017 Senior Lien Bonds and the Outstanding Senior Lien Bonds. See "SECURITY FOR THE 2017 SENIOR LIEN BONDS-Issuance of Additional Senior Lien Bonds" and "CAPITAL PROGRAMS."
Obligations Subordinate to Senior Lien Bonds. As described under "SECURITY FOR THE 2017 SENIOR LIEN BONDS-Covenants Against Lien on Revenues," the City has the right, at any time, to issue debt payable or secured by Revenues so long as such pledge is expressly junior and subordinate to the pledge of Revenues to the payment of Senior Lien Obligations. Indebtedness of the type described in the preceding sentence can be issued without limit as to nature or amount.
The City has authorized the issuance of Chicago O'Hare International Airport Commercial Paper Notes (the "Commercial Paper Notes") and Chicago O'Hare International Airport Credit Agreement Notes (the "Credit Agreement Notes"), respectively, in a combined aggregate principal amount outstanding at any one time of up to $1 billion. Pursuant to this authority, the City recently established a $420 million Commercial Paper Notes program and a $180 million Credit Agreement Note program. The Commercial Paper Notes and the Credit Agreement Notes (to the amount issued) are Junior Lien Obligations and subordinate to the 2017 Senior Lien Bonds and all other Senior Lien Obligations with respect to their claim on Revenues. The authorized and outstanding Commercial Paper Notes and Credit Agreement Notes are set forth in the table below. The Credit Agreement Notes arc issued pursuant to a revolving credit agreement and repayment of the amount outstanding would restore the credit capacity for ' future borrowings.

Lf.tter ok Credit Facilities Securing Indebtedness at O'Hare
The City has issued from time to time certain variable rate bonds and notes that arc supported by letter of credit facilities provided by banks for the payment of debt service and/or tender prices for such obligations. The City is obligated to reimburse the banks for any payments or draws under the letter of credit facilities. Set forth in the following table is information about the City's letter of credit facilities supporting Senior Lien Obligations at O'Hare. As reflected in such table, a reduction in the City's debt rating for the related debt below the level that is shown in the "Ratings Thresholds" column would constitute an event of default under the related bank agreement.

If an event of default is triggered due to a ratings downgrade or for any other reason, the subject bank would have the right to provide the bond trustee with a notice directing a mandatory tender of the related bonds. For such mandatory tender, the bond trustee would draw upon the letter of credit facility to fund the purchase price for such bonds. In such case, the bonds would be owned by the bank and would be immediately repayable at the option of the bank.

The United States Congress enacted the PFC Act in 1990, authorizing;a public-agency,; such: as
the City, which controls a commercial service aiq^ort to charge each paying passenger enplaning at such
aiiTJoftr(subjcct ^ PFC of $ 1\00, $2K)0: or $3.00. The1 purpose of the PFC is to
provide additional-''eapital-'ftrridihgi foKthe •'expahsib'h)'oP the 'national' airport system. The procee'ds-from PFCs are'to be used tb finance ciigible'airport-related'projccts'that preserve or enhance safety, capacity or security of the national air transportation system; reduce noise-from an airport that is part of such'system; or furnish opportunities for enhanced competition between or among air carriers.

'PFCs are collected oh behalf of airports by air carriers'.and their agents (the "Collecting Carriers") and remitted tb'-tnc City on a1 monthly- basis. On September l:,:'l 993, pursuant to'a PFC Approval^ the City began' to' impose PFCs af^Hareat^


56

The Wendell II. Ford Aviation Investment and Reform Act for the 21st Century ("AIR 21"), among other things, authorizes eligible public agencies, such as the City, to impose PFCs of $4.00 or $4.50 to finance PFC eligible projects, including the payment of debt service on indebtedness incurred to finance such projects, that cannot be paid for from funds reasonably expected to be available through the federal AIP. On April 1, 2001, pursuant to authorization contained in AIR 21 and amended PFC Approvals (as herein defined) received from the FAA, the City began imposing PFCs at O'Hare at the rate of $4.50 per eligible enplaned passenger. Regardless of the number of PFC applications which have been approved by the FAA, eligible public agencies, such as the City, only can collect a maximum of $4.50 from each eligible enplaning passenger.

Collection of the PFCs
A PFC may be collected from a passenger for no more than two boardings (i) on a one-way trip or (ii) in each direction of a roundtrip. The public agency may request exemption from the requirement to collect PFCs for a class of air carriers if the number of passengers enplaned by the carriers in the class constitutes no more than one percent of the total enplaned passengers annually at the airport at which the PFC is imposed. The City has requested and received an exemption from the collection of PFCs for air taxi operators at O'Hare. Air taxi operators have historically accounted for less than one percent of all PFC eligible enplanements at O'Hare.

Treatment of PFCs in Airline Bankruptcies. The PFC Act provides that PFCs collected by the Collecting Carriers constitute a trust fund held for the beneficial interest of the eligible public agency (i.e., the City) imposing the PFCs, except for any handling fee or retention of interest collected on unremitted proceeds. In addition, federal regulations require airlines to account for PFC collections separately and to disclose the existence and amount of funds regarded as trust funds for financial statements. However, the Collecting Carriers are permitted to commingle PFC collections with other revenues and are also entitled to retain interest earned on PFC collections until such PFC collections arc remitted.

In the event of a bankruptcy, the PFC Act, as amended in December 2003 by the Vision 100— Century of Aviation Reauthorization Act ("Vision 100"), provides certain statutory protections to eligible public agencies imposing PFCs, including the City, with respect to PFC collections. It is unclear, however, whether the City would be able to recover the full amount of PFC trust funds collected or accrued with respect to a Collecting Carrier in the event of a liquidation or cessation of business. Vision 100 requires an airline that files for bankruptcy protection, or that has an involuntary bankruptcy proceeding commenced against it, to segregate passenger facility revenue in a separate account for the benefit of the eligible public agencies entitled to such revenue. Prior to the amendments made by Vision 100 allowing PFCs collected by airlines to constitute a trust fund, at least one bankruptcy court indicated that PFC revenues held by an airline in bankruptcy would not be treated as a trust fund and would instead be subject to the general claim's of the unsecured creditors of such airline. In connection with another bankruptcy proceeding prior to Vision 100, a different bankruptcy court entered a stipulated order establishing a PFC trust fund for the benefit of various airports to which the bankrupt airline was not current on PFC payments. While Vision 100 should provide some protection for eligible public agencies in connection with PFC revenues collected by an airline in bankruptcy, no assurances can be given as to the approach bankruptcy courts will follow in the future. See "CERTAIN INVESTMENT CONSIDERATIONS—Effect of Airline Bankruptcy."

The City also cannot predict whether a Collecting Carrier operating at O'Hare that files for bankruptcy would have properly accounted for PFCs owed to the City or whether the bankruptcy estate would have sufficient moneys to pay the City in full for PFCs owed by such Collecting Carrier. Based on Vision 100, it is expected, although no assurance is given, that the City would be treated as a secured


57

creditor with respect to PFCs held by a Collecting Carrier which becomes involved in a bankruptcy proceeding. See "CERTAIN INVESTMENT CONSIDERATIONS—Effect of Airline Bankruptcy."

The Ci ty's PFC Approvals

Since 1993, the FAA has approved several PFC applications and amendments submitted by the City authorizing the City to use PFCs to pay (i) allowable costs of projects approved by the FA A for PFC funding ("Approved Projects"), including those Approved Projects financed or refinanced by the issuance of the Series 2001 PFC Bonds, the Series 2008 PFC Bonds, the Series 2010 PFC Bonds and the Scries 2011 PFC Bonds (each scries as defined in APPENDIX A - "GLOSSARY OF TERMS"), together with debt service on such bonds, and (ii) allowable costs of certain Approved Projects on a "pay as you go" basis. The City recently received PFC authority for the International Terminal expansion project.

As of the date of this Official Statement, the City has authority to impose and use at O'Hare up lo $6.93= billion ;in PFCs Based upon.:the City's current PFC authority,, the FAA :estimates .the PFC collection-.expiration date-to-be, July 1,-204.1. Sec Exhibit 5-7 in APPENDIX E - "REPORTOF THE AIRPORT-CONSULTANT" Tor a description of PFC Revenues anticipated to be received by the. City through- 2025. Although the City expects that it will obtain new PFC .Approvals; before its current authority-expires, no assurance can.be given that the City will be able to do so., Regardless, the2017B Senior Lien Bonds are also payable from and secured by a pledge of Revenues. See "SECURITY .FOR THE 2017 SENIOR LIEN BONDS ."

Capital Programs

Gl'.NF.RAL

The City has on-going capital programs at O'Hare that arc collectively referred to herein as the "Capital Programs." The Capital Programs include: (i) the OMP Airfield Projects; (ii) the 2017-2021 OP, including the Terminal 5 Expansion, the Multimodal Facility and ongoing repair and maintenance projects; and (iii) other recently announced Capital Programs, including the Concourse L Extension, the Hotel Development and the TAP. These Capital Programs and their funding are described herein and in the Report of the Airport Consultant. See APPENDIX E - "REPORT OF THE AIRPORT CONSULTANT." In addition to the Capital Programs, the City, in accordance with criteria established by the O'Hare Noise Commission, participates in an ongoing program of providing sound insulation to eligible schools and residences in the vicinity of O'Hare (the "OMP Noise Program"). Sec "CHICAGO O'HARE INTERNATIONAL AIRPORT-O'Hare Noise Compatibility Commission."
OMP Airfield Projects
Overview. The OMP Airfield Projects were designed to enhance both O'Hare and system-wide airport capacity. The FAA's final Environmental Impact Statement ("EIS") defines the purpose and the need for the OMP as addressing the projected needs of the Chicago Region by reducing delays at O'Hare, thereby enhancing capacity of the National Airspace System ("NAS"), and ensuring that existing and future terminal facilities and supporting infrastructure can efficiently accommodate airport users.
The OMP Airfield Projects involve changing the airfield from a layout with intersecting runways to a modern parallel runway system. The OMP, which includes the construction of one new runway, the relocation of three existing runways and the'extension of two existing runways, is being undertaken in phases that began in 2005. To date, three of the four runways have been completed and one of the two runway extensions has been completed. O'Hare has experienced a reduction in operational delays and an increase in airfield capacity with the completion of these OMP projects. The remaining OMP Airfield Projects include one runway (9R-27C) (under construction), and an extension to an existing.runway (9R-27L), which is expected to further reduce delays and increase capacity. See APPENDIX E - "REPORT OF THE AIRPORT CONSULTANT" for a more detailed discussion of the OMP.
Projected Sources and Uses of Funds for OMP Airfield Projects. Funding for the OMP Airfield Projects has been undertaken in phases. OMP Phase 1, a $3.2 billion project approved by the Airline Parties, included two runways and an extension and was completed in 2013. A $1.3 billion funding agreement with the Airline Parties for OMP Phase 2A included one runway and enabling projects for another future runway. This.phase is fully funded; the runway project was completed in October 2015 and the remaining projects are anticipated to remain within budget. Approximately $361.4 million of the cost of the remaining OMP Airfield Projects are assumed in the Report of the Airport Consultant to be funded by proceeds from future Senior Lien Obligations, assumed to be issued in 2018. Additional sources of funding for these projects include PFC Revenues (on a pay-as-you-go basis) and FAA AIP grant receipts. See APPENDIX E - "REPORT OF THE AIRPORT CONSULTANT" for a more detailed discussion of the sources arid uses of funds for the OMP Airfield Projects.
2017-2021 CLP .
Overview. The 2017-2021 CIP includes the Terminal 5 Expansion, the construction of the Multimodal Facility, and development projects at O'Hare that generally address O'Hare's ongoing capital needs. The total estimated cost of the 2017-2021 CIP projects is $2,268 billion (including the cost of the Terminal 5 Expansion and the Multimodal Facility).

Terminal 5 Expansion. The City is undertaking an expansion of and modifications to Terminal 5,
the International Terminal, to accommodate increased traffic and increased aircraft si/.e at O'Hare (the
"Terminal 5 Expansion"). The Terminal 5 Expansion increases both the number of gates (from 19 to 28)
and the size of gates at Terminal 5. The project includes an extension of the east concourse of
Terminal 5, which includes the addition of approximately 279,000 square feet of .gross floor area; the
addition of 9 aircraft parking positions and installation of associated passenger loading bridges; and the
extension/of sterile corridors feeding the FIS facility. The project also includes the expansion of the
existing terminal apron by/approximately 1.5 million square feet, increasing total linear-feet of gate
frontage by approximately 25 percent. The Terminal 5 Expansion also includes the reconfiguration of
gates on: the west concourse;of Terminal 5. Gates Ml through M6 arc anticipated to be modified to
accommodate eight narrow body aircraft and. includes:the. modification of existing passenger .loading
bridges and the addition of new passenger loading bridges. Existing Terminal 5 facilities are anticipated
to be modified to accommodate additional activity. Modifications to systems include the expansion of the
security screening checkpoint; the modification of the baggage system, ticket counter lobby facilities, and
FIS-'inspcction .areas; iahd other-projects. .! . ,
The City expects to ftilly fund the estimated $266.8: million cost of the projects comprising the

Concourse L Extension. In February 2016, the City announced a project to expand existing Concourse L in Terminal 3. Five new gates will be added to Concourse L to accommodate existing and future demand. The new Concourse L gates comprise the first expansion of gate capacity since Terminal 5, the International Terminal, was built in 1993; this is also the first domestic gate expansion since Terminal 1 was built in 1987.- The Concourse L Extension is expected to be completed in 2018 and is being funded directly by American Airlines.
Hotel Development. In June 2016, the City announced three hotel development projects to add capacity at OTIare. The projects include the construction of two new hotels and the modernization of the existing terminal hotel. CDA intends to develop a new hotel adjacent to the International Terminal, accessible to the ATS, with 300-400 rooms, 25,000-65,000 square feel of conference space, banquet rooms, and other amenities. A second 150-200 room hotel is expected to be developed by a third party as part of a new mixed-use commercial development adjacent to the Multimodal Facility and adjacent to a 200,000 square foot office complex. Both will also be accessible to the terminals via the ATS. Plans also exist for a renovation and modernization of the existing terminal hotel when the current lease expires in 2018. The total investment for the three development projects is estimated to be approximately $350 million, planned to be funded by a special facility loan backed by hotel revenues, and construction is expected to be complete between 2020 and 2022. A Request for Proposals is underway for an Operator Agreement for the modernization of the existing terminal hotel and for a new hotel located near Terminal 5.
Terminal Area Plan. In addition to near-term gate expansion projects, long-term terminal development and redevelopment options are being evaluated as part of a recently announced TAP. The City's goals include strengthening O'Hare's connectivity, capacity, and efficiency; improving passenger experience; and modernizing existing terminals and their functional and commercial spaces. The City and airline representatives are collectively evaluating terminal development and phasing options. Significant investments in increasing airfield capacity have been made to address airfield delays and to provide long-term capacity. Concurrently, the airline industry has pursued several changes that have built additional pressure on O'Hare's existing terminal infrastructure and the TAP could provide increased capacity of aircraft gates and terminal processing areas, while also meeting functional needs in several areas. Funding sources for the TAP are anticipated to include the proceeds of future Airport Obligations and other funding sources that have not yet been identified.
Management Approach for Capital Programs

For the OMP, United Airlines and American Airlines established a tiered management structure with each tier, having specific review and approval authority. The OMP Executive Working Group, comprised of three City representatives. and two airline, representatives, meets ,to review and discuss program scope, schedule, budgets, and funding A committee of the. Airline Parties retains the right to approve increases in project component scope and budget of more than 10 percent, any financial commitment of over $5 million, and project delivery methods if construction value is greater than $20 million.
For all other Capital Programs, the City employs a construction manager to coordinate, supervise and inspect capital project construction. The construction manager prepares and maintains records on the progress of each capital project. The City and the construct ion manager oversee all work to ensure that each project is constructed in accordance with its plans and. specifications within the timelines set forth in the construction schedule. In addition, the Airline Parties designate a construction representative to assess the construction and operational impact of capital projects and to participate in the evaluation of design and construction.

Federal Legislation, State actions and Proposed South Suburban airport

Federal Legislation. On July 15, 2016, President Obama signed the "FAA Extension, Safety and Security Act of 2016" into law. The law reauthorizes the Federal Aviation Administration ("FAA") operations and programs through September 30,2017. On May 5, 2017, Public Law Number 115-31, the Consolidated Appropriations Act, 2017, was signed into law which authorizes appropriations that fund the operation of the Federal Government through September 30, 2017.

62

General Fac tors Affecting Level of Airline Traffic and Revenues
The 2017 Senior Lien Bonds are payable from and secured by a pledge of Revenues and certain Funds and Accounts held under the Senior Lien Indenture. Revenues arc dependent primarily on the level of aviation activity and enplaned passenger traffic at O'Hare. Key factors affecting airline traffic at O'Hare include, among others, (i) population growth and the economic and political conditions of the region and the nation, (ii) the financial health of the airline industry and of individual airlines, (iii) airline service and route networks, (iv) capacity of the national air traffic control system and of O'Hare and other competing airports, (v) national and international disasters and hostilities, (vi) safety concerns arising from international conflicts, the possibility of terrorist or other attacks, and (vii) various other local, regional, national and international economic, political and other factors. Many of these factors, most of which are outside the City's control, are discussed in detail in APPENDIX E - "REPORT OF THE AIRPORT CONSULTANT." If aviation activity at O'Hare does not meet forecast levels, a corresponding reduction may occur in Revenues (absent an increase in O'Hare rentals, fees and charges).

UNCERTAINTIES OF THE AIRLINE INDUSTRY

General. The City's ability to collect Revenues is affected by the dynamics of the airline industry, which also affect the ability of the Airline Parties, individually and collectively, to meet their respective obligations under the Airport Use Agreements and other arrangements.
Historically, the financial performance of the airline industry generally has correlated with the strength of the national and global economy. Certain factors that may materially affect O'Hare.and the airlines include, but are not limited to, (i) growth of population and the economic health of the region and the nation, (ii) airline service and route networks, (iii) national and international economic and political conditions, (iv) changes in demand for air travel, (v) service and cost competition, (vi) mergers and bankruptcy- of any airlines, (vii) the availability and cost of aviation fuel and other necessary supplies, (viii) levels'of air fares, fixed costs and capital requirements, (ix) the cost and availability of financing, (x) the capacity of the national air traffic control system, (xi) national and international disasters and hostilities, (xii) public health concerns, such as the spread of influenza and severe acute respiratory syndrome; (xiii) the cost and availability, of employees and labor relations within the airline industry, (xiv) regulation by the federal government, (xv) environmental risks, noise abatement concerns and regulation, (xvi) acts of war or terrorism, (xvii) aviation accidents, and (xviii) other risks. As a result of these and other factors, many airlines have operated at a loss in the past and many (including some that served O'Hare) have filed for bankruptcy, ceased operations and/or merged with other airlines. In addition, the so-called legacy carriers have taken many actions to restructure and reduce costs including reducing their workforce, renegotiating their labor agreements, reducing routes served, consolidating connecting activity and replacing mainline jets with regional jets.
Financial Condition of Airlines Serving O'Hare. Many of the airlines serving O'Hare were impacted by the global economic downturn and recession that occurred between 2008 and 2009, and most major domestic airlines suffered significant financial losses. While the U.S. and global economies generally have rebounded, there can be no assurances that any such rebound will continue, or that other national "or international fiscal concerns will not have an adverse effect on the airline industry. Current and future-financial and operational difficulties encountered by the airlines serving O'Hare (most notably United Airlines arid its regional -affiliates,- which" accounted for approximately 44.2 percent of the enplaned passengers at O'Hare in 2016, and American Airlines and its regional affiliates, which accounted for approximately 35.8 percent of the enplaned passengers at O'Hare in 2016), could have a material adverse effect on operations at, and the financial condition of, O'Hare. If cither United Airlines or American Airlines were to cease operations at O'Hare for any reason or eliminate or reduce O'Hare's



63

status as a connecting hub, the current level of activity of such airline may not be replaced by other airlines.
Cost of Aviation Fuel. Airline earnings arc significantly affected by the price of aviation fuel.
Any increase in fuel prices results in an increase of airline operating costs. Fuel prices continue to be
impacted by, among other things, political unrest in oil-producing parts of the world, increased demand
for fuel caused by rapid growth in certain global economies, such as China and India, currency
fluctuations and changes in demand for and supply of oil worldwide. Significant fluctuations and
prolonged periods of increases in the cost of aviation fuel have had material adverse effects on airline
profitability, causing airlines to reduce capacity, fleet and personnel, as vvell as increase, fares and institute
additional fees,, such as checked baggage fees, all of which may decrease demand for airtravcl. Although,
at,-present, aviation: fuel prices have stabilized, no assurance can be given that,such fuel prices will not
increase in,the future, thereby negatively impacting airline earnings and operations." : ¦;: ¦,- •-

Airline Mergers, Acquisitions and Alliances. In response to competitive pressures and increased
costs, airlines have merged and acquired competitors in an attempt to combine operations in order to
increase cost synergies and become more competitive. In 2009, Delta merged with Northwest Airlines.
In i-2010, : UnitedirAirlines .'and Continental Airlines -merged. In. 2015,, American arid > US Airways
completed theirs merger which created-the .largest airline in the world in terms of operating, revenue; and
revenue passenger miles. - Tn-addition, alfof the large U.S. airlines are members of.alliances! with foreign-
flag airlines, which alliances, and other marketing arrangements, provide airlines with many of the
advaritages of mergers. Alliances lypically involve marketing,.code-sharing, and schedulingiarrangements

See APPENDIX C - "SUMMARY OF C ERTAIN PROVISIONS QF THE AIRPORT USEAGREEMENTS-Gencral,Commitment to Pay Airport Fees and,Charges."
Capacity of National Air Traffic Control and Airport System . ¦ . ..

, i' Capacity limitations, of the national,.air.traffic control systems .continue to cause aircraft delays and restrictions, both on the number of aircraft movements in certain air traffic routes and on the number


64

of landings and takeoffs at certain airports. These restrictions affect airline schedules and passenger traffic nationwide. The FAA has made certain improvements to the computer, radar and communications equipment of the air traffic control system in recent years, but no assurances can be given that future increases in airline and passenger traffic will not again adversely affect airline operations.

Expiration of Airport Usf: agreements
The expiration date of the Airport Use Agreements is May 11, 2018. Substantially all of the debt service on the 2017 Senior Lien Bonds and the Outstanding Senior Lien Bonds becomes due after such date. It is not possible to predict whether any airline will be contractually obligated to make payments, including, among other things, for debt service on the 2017 Senior Lien Bonds, the Outstanding Senior Lien Bonds or any other Senior Lien Bonds after the expiration dale of the Airport Use Agreements in 2018. Upon the expiration of the Airport Use Agreements, the City may enter into extensions of such agreements with the airlines, enter into new agreements with the airlines, or impose rates and charges upon the airlines by City ordinance. The City has covenanted in the Senior Lien Indenture (which extends beyond the expiration of the Airport Use Agreements) to establish rentals, rates and other charges for the use and operation of O'Hare such that Revenues (including rentals, fees and charges imposed on the airlines), together with certain other moneys deposited with the Trustee, are sufficient to pay Operation and Maintenance Expenses at O'Hare and to satisfy the debt service coverage covenants contained in the Senior Lien Indenture. See "SECURITY FOR THE 2017 SENIOR LIEN BONDS-Debt Service Coverage Covenants."

Capital Programs Costs and Schedule
The estimated costs of, and the projected schedule for, the projects in the Capital Programs for O'Hare depend on various sources of funding, and are subject to a number of uncertainties. The ability of the City to complete these projects within the current budgets and on the current schedules may be adversely affected by various factors including: (i) estimating errors, (ii) design and engineering errors, (iii) changes to the scope of the projects, (iv) delays in contract awards, (v) material and/or labor shortages, (vi) delays due to airline operational needs, (vii) unforeseen site conditions, (viii) adverse weather conditions, (ix) contractor defaults, (x) labor disputes, (xi) unanticipated levels of inflation, (xii) litigation and (xiii) environmental issues. No assurance can be'given that the costs of the projects will not exceed the current budget for these projects or that the completion will not be delayed beyond the currently projected completion; dates. At present, the City is unable to estimate the costs associated with each of the risks identified above , and the total impact of these risks if such'events were to occur. In addition, the City may ultimately decide not to proceed with certain capital projects or may proceed with them on a different schedule, resulting in different results than those included in the projections shown in the Report of the Airport Consultant.

Future Indebtedness
As described under "CAPITAL PROGRAMS," the City expects that it will need to incur additional indebtedness, including the issuance of Senior Lien Bonds, other Airport Obligations, and PFC Obligations, to finance the Capital Programs. Also the City's plans of finance for the Capital Programs assumeThat PFC Revenues would be available in certain amounts and at certain times for the payment of a portion of the anticipated costs of such capital projects on a "pay as you go " basis and for the payment of a portion of the debt service on Senior Lien Bonds, including without limitation the 2017B Senior Lien Bonds and other Senior Lien Bonds, to the extent such Senior Lien Bonds are payable from PFC Revenues. See "CAPITAL PROGRAMS." No assurance can be given that these sources of funding actually will be available in the amounts or on the schedules assumed. For a discussion of the availability of PFC Revenues, see "-Availability of PFC Revenues" below.


65

The City's plans of finance with respect to the Capital Programs assume that FAA LOI Grants and FAA AfP Grants would be available in certain amounts and at certain times for the payment of a portion of the anticipated costs of such capital projects on a "pay as you go" basis and for the payment of a portion of the debt service on the Senior Lien Bonds, including without limitation the 2017C Senior Lien Bonds and other Senior Lien Bonds to the extent such Senior Lien Bonds are payable from Grant Receipts. FAA LOI Grants and FAA AIP Grants.are subject to congressional appropriation, as well as automatic spending cuts, known as sequestration as described below in "-Additional Federal Authorization and'Funding Considerations." Although the City considers such assumptions in its plans of finance to be 'reasonable, such assumptions are inherently subject to certain uncertainties and contingencies'Actual'FAA LOI Grant Receipt and'FAA AIP'Grant Receipt funding levels and timing may.-vary and such, differences may be material. See "CAPITAL PROGRAMS-GIMP Airfield Projects" and APPENDIX E - "REPORT OF THE AIRPORT CONSULTANT "

66

staffing shortages and traffic delays and cancellations at airports across the United Slates. See "FEDERAL LEGISLATION, STATE ACTIONS AND PROPOSED SOUTH SUBURBAN AIRPORT—Federal Legislation."

The FAA may, from time to time, and following consultation with the City, amend the Grant Letter of Intent to adjust the anticipated grant schedule or the maximum federal obligation, or both. Such adjustment may be made by the FAA when occasioned by changes in the actual allowable costs of a project, in the actual time required to complete a project, in actual or estimated future obligating authority or otherwise, when determined in the FAA Administrator's discretion to be in the best interests of the United States.

Grant Letter of Intent Not A Binding Contrac t

The Grant Letter of Intent is not an obligation of the United States of America under Section 1501 of Title 31 United States Code, as amended, nor is it deemed to be an administrative commitment for funding. Rather, the Grant Letter of Intent reflects only the FAA's current intent to make grants to the City to reimburse the City for capital improvements, including the OMP. The Grant Letter of Intent is not a binding grant agreement. Even if the FAA receives sufficient appropriations to make the grants described in the Grant Letter of Intent, the FAA has no legal obligation to make such grants. In addition, the AIP, pursuant to which the Grant Letter of Intent payments are to be made, is subject to revision by the U.S.- Congress. Such an amendment could affect payments to be made to the City under the Grant Letter of Intent.

The FAA may, from time to time, following consultation with the City, amend the Grant Letter of Intent to adjust the anticipated grant schedule or the maximum federal obligation, or both. Such adjustment may be made by the FAA when occasioned by changes in the actual allowable costs of the OMP, in the actual time required to complete the OMP, in actual or estimated future obligating authority or otherwise, when determined in the FAA Administrator's discretion to be in the best interests of the United States.

Amount of Grant Letter of Intent Payments Depend on Eligible Expenditures at O'Hare

The Grant Letter of Intent evidences the FAA's intent to make grants to reimburse the City for eligible expenditures and the maximum amount of grants available for such reimbursement. The estimated grant schedule represents the maximum eligible reimbursement grants with respect to any Federal Fiscal Year. In addition lo the adjustments described in the immediately preceding section, the actual Grant-Receipts received by the City in any one Federal Fiscal Year will also be dependent on the City's timely expenditure of amounts which are eligible for reimbursement under the Grant Letter of Intent and the timely application by the City for reimbursement. If the City has not expended funds and requested reimbursement prior to the end of any of the Federal Fiscal Years specified in the Grant Letter of Intent in an amount at least equal to the then-available amount of grants under the Grant Letter of Intent for that Federal Fiscal Year, the City can request an amendment to the Grant Letter of Intent to shift any unused moneys to the next Federal Fiscal Year.

Grant Receipts May Be Reduced By Events Outside of City's Control

Events outside the control of the City could cause the amount of Grant Receipts available to be received by the City pursuant to the Grant Receipts to be lower than the debt service requirements on the 2017C Senior Lien Bonds anticipated to be paid from such Grant Receipts. In such event, principal and interest on the 2017C Senior Lien Bonds would be paid from Revenues. The City would not be obligated to take any action to cause the Grant Receipts available to be received by the City pursuant to the Grant

67

Letter of Intent or other Grant Receipts to be at least equal to the debt service requirements on the 2017C Senior Lien Bonds anticipated to be paid from the Grant Letter of Intent and other Grant Receipts. See "Grant Receipts Subject to Federal Authorization/Appropriation, Sequestration." above for a discussion of certain events which could affect the amount of Grant Payments available to be received by the City.

Termination of Grant Letter of Intent for Failure to Comply with Conditions

The City is required, as a condition for its receipt of reimbursement as specified in the Grant Letter of Intent, to comply with all statutory and administrative requirements under the Airport and Airway Improvement Act and the regulations thereunder. Failure to comply with such requirements, or failure to proceed with the OMP in a timely manner, may lead to reductions in amounts payable under the Grant Letter of Intent or a revocation of the Grant Letter of Intent. Reimbursement may also be affected by: failure., to icomply with other existing grant agreement assurances. In the event of any such failure by the City, or.any other action by the City which-threatens the federal-contribution to the OMP, the FAA may.-pursue.all remedies-available in law or equity, including, but not: limited to, thewithholding of future payments iUrider the Grant Letter of Intent:

Availability of PFC Revenues

Capital Programs assume that PFC Revenues would be available in certain amounts and at certain times
for the payment of a portion of the anticipated costs of such capital projects on a "pay-as-you-go" as well
as to-secure additional Airport Obligations needed to fund such projects.In addition, the Report of the
Airport (Consultant-,; ¦which, se.ts forth; certain; ProjectipnsJregarding Q'-Harc,, assumes that certain available
PFC .Revenues not, otherwise- pledged- to.pay-PFC Obligations, Senior Lien Bonds, and other payment

service/.oniSuchfO.bligations.tNo assurance .can-be '-given-' that PFQ i Revenues -.will be( (available- in-, the amounts or on the schedules assumed.

.„ .The; ability of the City to collect sufficient PFC Revenues depends upon a number*of factors, inGludmg^without^imi
Carriers and the efficiency and ability of the. Collecting, Carriers to collect and remit-PFCs to the City. The City;relies, on.the. -Collecting [Gamers' collection and, remittance, of PFCs, and both, the City and the FAA rely upon the airljncs' reports of enplanements and colleetions.

; ; Under, the terms :pf the. PFCAct, the, FAA may germinate the. City's authority to impose a RFC if
the City's RFC, Reyenues,are not^ wjth the,FAA's,approval;
the PFC Act,or foe-/egulations;promulgated -thereunder, or if;the-Gity rptheiwisei(viplates the'PF,C Act -or regulations. The FAA may.also .terminate the City's authority,to impose a PFC for a,violation by the:City of the, Airport Noise.,and Capacity Act., The,.PFC. termination .provisions-contained,;in the regulations provide -both informal and formal procedural safeguards.
The PFC Act provides that PFCs collected by the airlines constitute a trust fund held for the beneficial interest of the eligible agency, (i.e.-, the-City) imposing the PFCs, .except for any handling fee or retention of interest collected on unremitted proceeds. Furthermore, the FAA's PFC regulations require Collecting. Carriers to account for RFC collections separately, and further indicate that such funds are to be regarded, as trust funds.heldtby the,Collecting.Carricrs for.the beneficial, interest, of -the public agency imposing,the. PFC... Recent •bankruptcy court decisionsjipwever, indicate that in a.bankruptcy proceeding involving a Collecting, Gamer, it is likely that PFCs will not.be treated as trust funds and that-airports arc not entitled to any priority over other creditors of the Collecting Carrier,as to such funds. For more


68

detailed information on treatment of PFCs in bankruptcy, see "PFC PROGRAM AT O'HARE-Collection of the PFCs."
Additional Federal Authorization and Funding Considerations
The City receives federal funding for O'Hare not only in connection with FAA AIP Grants and PFC authorizations, but also in the form of funding for the TSA, air traffic control and other FAA staffing and facilities. On July 15, 2016, President Obama signed the "FAA Extension, Safety and Security Act of 2016" into law. This law reauthorizes FAA operations and programs through September 30, 2017. In the event that the FAA Extension, Safety and Security Act of 2016 were to expire without a long-term reauthorization or another short-term extension, during such period FAA programs would be unauthorized, including FAA programs providing funding for O'Hare. The City is unable to predict whether legislation to extend or reauthorize this statute or otherwise continue FAA programs will be adopted prior to the scheduled expiration date, if not so adopted, the duration of any resulting period of de-authorization, and the impact on O'Hare finances which might result therefrom.
Federal funding is also impacted by sequestration, a budgetary feature first introduced under the federal Budget Control Act of 2011. Unless changed by the United States Congress from time to time, sequestration is a multi-year process and could continue to affect FAA, TSA and CBP budgets and staffing, resulting in staffing shortages and traffic delays and cancellations at airports across the United Stales. The full impact of sequestration on the aviation industry and O'Hare, generally, resulting from potential layoffs or further furloughs of federal employees responsible for federal airport security screening, air traffic control and CBP, is unknown at this time.
Regulations and Restrictions Affecting O'Hare
The ioperations of O'Hare and its ability to generate revenues are affected by a variety of contractual,-: statutory and regulatory restrictions and limitations, including, without limitation, the provisions of-the Airport Use Agreements, the PFC Act and other extensive federal legislation and regulations applicable to all airports in the United States. There is no assurance that there will not be any change -in, interpretation of, or addition to any such applicable laws, regulations and provisions. Any such change, interpretation or addition may have a-material adverse effect; either directly or indirectly, on O'Hare, which could materially adversely affect O'Hare's operations or financial condition.
In addition, following the events of September 11, 2001, O'Hare also has been required to implement enhanced security measures mandated by the FAA, TSA and the Department of Homeland Security. It is not possible to predict whether future restrictions or limitations on Airport operations will be imposed, whether future legislation or regulations' will affect anticipated federal funding or PFC collections for capital projects for O'Hare, whether additional requirements will be funded by the federal government or require funding by the City or whether such restrictions or legislation or regulations would adversely affect Revenues.
Climate change concerns have led, and may continue to lead, to new laws and regulations at the federal and state levels that could have a material adverse effect on the operations of O'Hare and on the airlines operating at O'Hare: The United States Environmental Protection Agency (the "EPA") has taken steps toward regulation of greenhouse gas ("GHG") emissions under existing federal law. These steps may lead to further regulation of aircraft GHG emissions. No assurances can be given as to what any EPA emissions standards governing O'Hare or the airlines could be or what effect those standards may have on the City or the airlines operating at O'Hare.

Competition

O'Hare competes with other U.S. airports for both domestic and international passengers. Portions of O'Hare's Air Trade Area are serviced by Midway and Mitchell. In 2016, Midway had cnplanemcnts representing approximately 25.3 percent of Chicago originating passenger traffic and approximately 18.7 percent of Chicago connecting passenger traffic. Midway is expected to continue to be a competitor for the Chicago region's domestic market. See "CHICAGO O'HARE INTERNATIONAL AIRPORT-Othcr Commercial Service Airports Serving the Chicago Region."
. International passengers are also significant at.O'Hare; making up approximately 15.1% of all passenger enplanements in 2016. International, air travel, may :bc, more casiiy. disrupted by political instability, terrorist activities, currency fluctuations and other factors outside the control of the City. The City cannot predict-whether the level of international passengers will remain stable or will grow, nor what events', .domestic-.or international, may adversely affect such air traffic:;. See APPENDIX E t "REPORT OF THE AIRPORT CONSULTANT-Air Traffic-Factors Affecting Aviation Demand at the Airport-Regional Airports."

/j,,.- ;.y\Unfunded¦¦Pensions.-fl\ic Retirement- Funds have significant imfundedjiabilite ratios. The City's contributions to the Retirement Funds-in-accordance with the Pension Code have not been sufficient, when combined with employee contributions and investment returns, to offset increases in the Retirement Funds' liabilities, which has contributed to the significant underfunding of the


70

Retirement Funds. Moreover, the contributions to the Retirement Funds in accordance with the Pension Code have had the effect of deferring the funding of the Retirement Funds' liabilities, which increases the costs of such liabilities and the associated financial risks, including the risk that each Retirement Fund will not be able to pay its obligations when due. Furthermore, increases in the City's contributions to the Retirement Funds (such as those scheduled to occur under Act 1495, as modified by Act 506) caused the City to increase its revenues and may require the City to further increase its revenues, reduce its expenditures, or some combination thereof, which may impact the services provided by the City or limit the City's ability to generate additional revenues for other purposes in the future

In addition, the actuaries for MEABF and LABF project that such Retirement Funds will not have sufficient assets on hand to make payments to beneficiaries beginning in 2025 and 2027, respectively, based on the provisions of the Pension Code currently in effect. The City makes no prediction as to the impact of the insolvency of MEABF or LABF on the amount of the City's contributions to these Retirement Funds. However, should the City be required to contribute the amounts necessary to fund directly such payments to beneficiaries on a pay-as-you-go basis upon the insolvency of such Retirement Funds, the amount of the City's contributions to MEABF and LABF would substantially increase.

Overlapping Taxing Districts. A number of governmental units and other public bodies share in varying degrees a common tax base, including property taxes, with the City. The City does not control the amount or timing of the taxes levied by these overlapping taxing districts. Depending on the amount of such increasc(s), an increase in the amount of taxes by these overlapping taxing districts could potentially be harmful to the City's economy and/or may make it more difficult for the City to increase taxes and maintain essential or necessary City services.

Municipal Bankruptcy
State-Law Authorization. Municipalities, such as the City, cannot file for protection under the U.S. Bankruptcy Code unless specifically authorized to be a debtor by state law or'by a governmental officer or organization empowered by stale law to authorize such entity to be a debtor in a bankruptcy proceeding.' State law does not currently permit municipalities to be a debtor in a bankruptcy proceeding: From time to time, legislation has been introduced in the Ulinois General Assembly which, if enacted, would permit Illinois municipalities to be debtors in bankruptcy. The City is unable to'predict whether the Illinois General Assembly will adopt any such legislation or the form of such legislation if enacted.
Special Revenues. Although the City can provide no assurances, the City believes that Revenues and Other Available Moneys currently pledged by the City under the Senior Lien Indenture constitute "special revenues, " as defined in Section 902(2) of the U.S. Bankruptcy Code, and therefore, pursuant to Section 928(a) of the U.S. Bankruptcy Code, any and all of such pledged Revenues and Other Available Moneys currently pledged by the City under the Senior Lien Indenture acquired by the City after the commencement of a case by the City under Chapter 9 of the U.S. Bankruptcy Code would remain subject to the lien of the Senior Lien Indenture and could not lawfully be used by the City other than in compliance with the Senior Lien Indenture. Under Section 922(d) of the U.S. Bankruptcy Code, the application by the City of "special revenues " under the terms of the Senior Lien Indenture would not be subject to stay after the commencement by the City of a case under Chapter 9 of the U.S. Bankruptcy Code. Sec "SECURITY FOR THE 2017 SENIOR LIEN BONDS-O'Hare Revenues Must Be Used For Airport Purposes."
Force Majeure Events Affecting the City and O'Hare
There are certain unanticipated events beyond the City's control that could have a material adverse effect on the City's operations and financial condition, or on O'Hare's operations and financial


71

condition, if they were to occur. These events include fire, flood, earthquake, epidemic, adverse health conditions or other unavoidable casualties or acts of God, freight embargo, labor strikes or work stoppages, civil commotion, new acts of war or escalation of existing war conditions, sabotage, enemy action, pollution, unknown subsurface or concealed conditions affecting the environment, and any similar causes. No assurance can be provided that such events will not occur, and, if any such events were to occur, no prediction can be provided as to the actual impact or severity of the impact on the City's operations and financial condition or on O'Hare's operations and financial condition, as applicable.
Enforcement actions
The remedies available, to bondholders upon nonpayment of principal of or interest on the 2017 Senior Lien Bonds arc in many respects dependent upon judicial enforcement actions which are .often subject ,to discretion and delay. See APPENDIX B "SUMMARY-OF CERTAIN PROVISIONS OF THE SENIOR LIEN INDENTURE - Remedies."

See "INTRODUCTION - Report of the Airport Consultant'; and APPENDIX E -"REPORT OF THE AIRPORT CONSULTANT."
The Projections are based, in part, on historic data from sources considered by the Airport Consultant to,he reliable, but,the accuracy of these .data has not been .independently, verified. The Projections are based on assumptions made by the . Airport Consultant concerning Tutu re events and


72


/
circumstances which the Airport Consultant believes are significant to the Projections but which cannot be assured. Therefore, the actual results achieved may vary from the Projections, and such variations could be material.

Limited Liability Subordina tion
As described under the caption "SECURITY FOR THE 2017 SENIOR LIEN BONDS," the 2017B Senior Lien Bonds are also payable from and secured by a pledge of the 20I.7B Pledged PFC Revenues to be derived from a subordinate pledge of PFC Revenues, including moneys to be withdrawn from the PFC Capital Fund. The pledge of PFC Revenues and moneys in the PFC Capital Fund as the source of the 2017B Pledged PFC Revenues is subject to (i) the prior and superior pledge of and lien on the PFC Revenues and the moneys in the PFC Capital Fund as security for the payment of the outstanding PFC Obligations and any future Series of PFC Obligations, (ii) the payments by the City pursuant to the Compact, (iii) the City's right to issue additional Senior Lien Obligations that are also secured by PFC Revenues, including moneys to be withdrawn from the PFC Capital Fund, on a parity with the 2017B Senior Lien Bonds, and (iv) the City's right to issue Subordinated PFC Obligations that are secured by a pledge of and lien on the PFC Revenues and the moneys in the PFC Capital Fund that are superior to the pledge and lien created by the Sixtieth Supplemental Indenture. Subject to certain conditions set forth in the PFC Indenture, the City may in the future issue (a) additional PFC Obligations that will be senior and superior to the claim of the 2017B Pledged PFC Revenues and (b) Subordinated PFC Obligations (including additional Commercial Paper Notes) that may be secured by a pledge of and lien on the 2017B Pledged-PFC Revenues and moneys in the PFC Capital Fund that is senior and superior to the pledge and lien on the 2017B Pledged PFC Revenues securing the 2017B Senior Lien Bonds. See "SECURITY FOR THE 2017 SENIOR LIEN BONDS—Certain Provisions of the PFC Indenture—Issuance of PFCObligations." i

FORWARD-LOOKING STATEMENTS

This¦ Official Statement contains certain statements relating to future results that are forward-looking statements. When used in this Official Statement, the words "estimate, " "intend, " "expect'' and similar expressions identify forward-looking statements. Any forward-looking statement is subject to uncertainty and risks-that could cause actual 'results to differ, possibly materially, from those contemplated in such forward-looking statements. Inevitably, some assumptions used to develop forward-looking statements will not be realized or unanticipated events and circumstances may occur. Therefore, bondholders and potential investors should be aware that there are likely to be differences between forward-looking statements and actual results; those differences could be material. The City does not undertake any obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise. See "INTRODUCTION - Regarding Use of the Official Statement."

LITIGATION

Except for the matter described below, there is no litigation pending or threatened against the City relating to the City's operation of O'Hare, the issuance, sale, or delivery of the 2017 Senior Lien Bonds, the validity or enforceability thereof, or the implementation, construction or operation of the OMP or the 2017-2021 CIP projects, including the projects financed with the proceeds of the 2017 Senior Lien Bonds, other than various legal proceedings (pending or threatened) which may have arisen or may arise out of the ordinary course of business of O'Hare. The City expects that the final resolution of such legal proceedings arising in the ordinary course of business will not have a material adverse effect on the financial position or the results of operation of O'Hare.

Riser v. Citv of Chicago. Case No. 2015-L-009955 (Cook Co. Cir. CU. On October 1, 2015, 61 homeowners in Bcnsenville filed a complaint alleging a taking of their property due to noise and disruption from aircraft overflights arriving and departing from the new Runway 10C-28C at O'Hare. Following multiple motions to dismiss filed by the City and changes of venue, Plaintiffs filed their third amended complaint. In it, they assert a single cause of action: inverse condemnation under the Illinois Constitution. Plaintiffs request relief in the form of compensation for the value of the property taken and the diminution in value to the remaining property not taken. On June 7, 2017, the Court denied the City's motion to dismiss the third amended complaint under 735 ILCS 5/2-619, and ordered he City to answer plaintiffs' complaint by July 5, 2017. The City intends to vigorously defend this law suit. The City.isiunable to express an opinion at this time concerning the outcome of (he above matter or the City's liability, if any, in connection therewith.
There arc, from time to time, lawsuits that, arise out of thc; various construction contracts entered into, in- connection withconstruction projects at O'Hare The City, however, does: not believe that any sums that may.be recovered would have a material adverse, impact on the financial condition of O'Hare.

The City has covenanted to comply with all requirements that must'be-, satisfied'in order for the interest on the 2017 Senior Lien Bonds to be excludable from gross income for federal income tax purposes. Failure to comply with certain of such covenants could cause interest on the 2017 Senior Lien Bonds to become includible in gross income for federal income tax purposes retroactively to the date of issuance of the 2017 Senior Lien Bonds.
Subject to the City's compliance with the above-referenced covenants, under present law, in the
respective .opinions of Co-Bond Counsel: - . ; .
(i) interest oh the 2017A Senior Lien Bonds, 2017B'Senior Lien Bonds and 2017C Senior •• . Lien.-Bondsj is excludable .from .gross income of the owners thereof for federal income tax purposes and is not included as an item of tax preference in computing the federal alternative minimum tax for individuals and corporations, but Co-Bond Counsel express no opinion as to

74

whether interest on the 2017A Senior Lien Bonds. 2017B Senior Lien Bonds and 2017C Senior Lien Bonds is taken into account in computing adjusted current earnings, which is used in determining the federal alternative minimum tax for certain corporations, and

(ii) interest on the 2017D Senior Lien Bonds is excludable from gross income of the owners thereof for federal income tax purposes, except for interest on any 2017D Senior Lien Bond for any period during which such 2017D Senior Lien Bond is owned by a person who is a substantial user of the facilities financed thereby or any person considered to be related to such person (within the meaning of Section 147(a) of the Internal Revenue Code of 1986, as amended), but such interest is included as an item of lax preference in computing the federal alternative minimum tax for individuals and corporations.

In rendering their opinions, Co-Bond Counsel will rely upon certifications of the City with respect to certain material facts within the City's knowledge and upon the mathematical computation of the yield on the 2017 Senior Lien Bonds and the yield on certain investments by Robert Thomas, CPA LLC, Certified Public Accountants. Co-Bond Counsel's opinions represent their respective legal judgments based upon their independent review of the law and the facts that they each deem relevant to render such opinions and are not a guarantee of a result.

Ownership of the 2017 Senior Lien Bonds may result in collateral federal income tax consequences to certain taxpayers, including, without limitation, corporations subject to the alternative minimum tax, corporations subject to the branch profits tax, financial institutions, certain insurance companies,1 certain S corporations, individual recipients of Social Security or Railroad Retirement benefits and taxpayers who may be deemed to have incurred (or continued) indebtedness to purchase or carry tax-exempt obligations-. Prospective purchasers of the 2017 Senior Lien Bonds should consult their tax advisors as to the applicability of any such collateral consequences.

>-! The issue price for original issue discount (as further discussed below) and market discount purposes (the "OID Issue Price") for each maturity of the 2017 Senior Lien Bonds is the price at which a substantial amount of such maturity of the 2017 Senior Lien Bonds is first sold to the public (excluding bond houses and brokers and similar persons or organizations acting in the capacity of underwriter, placement agent or wholesalers). The OID Issue Price of a maturity of the 2017 Senior Lien Bonds may be different from the price set forth, or the price corresponding to the yield set forth, on the cover page hereof.

- If the OID Issue Price of a maturity of the 2017 Senior Lien Bonds is less than the principal amount payable at maturity, the difference between the OID Issue Price of each such maturity, if any, of the 2017 Senior Lien Bonds (the "OID Bonds") and the principal amount payable at maturity is original issue discount.

For an investor who purchases an OID Bond in the initial public offering at the OID Issue Price for such-maturity and who holds such OID Bond to its stated maturity, subject to the condition that the City complies with the covenants discussed above, (a) the full amount of original issue discount with respect to such OID Bond constitutes interest which is excludable from the gross income of the owner thereof for federal income tax purposes (except in the case of an owner of 2017D Senior Lien Bonds who is a substantial user of the facilities financed thereby or any person considered to be related to such person within the meaning of Section 147(a) of the Code); (b) such owner will not realize taxable capital gain or market discount upon payment of such OID Bond at its stated maturity; (c) in the case of the 2017A Senior Lien Bonds, 2017B Senior Lien Bonds and 2017C Senior Lien Bonds, such original issue discount is not included as an item of tax preference in computing the alternative minimum tax for individuals and corporations under the Code, but owners of such OID Bonds should consult their own tax advisors as to

75

whether such original issue discount is taken into account in computing adjusted current earnings, which
is used in determining the federal alternative minimum tax for certain corporations; (d) in the case of the

Appendix C

SUMMARY OF CERTAIN PROVISIONS OF THE AIRPORT USE AGREEMENTS


























[Tins Page Intentionally Left Blank]
Appendix C
Summary of Certain Provisions of the Airport Use Agreements

The following is a summary of certain provisions of the Airport Use Agreements, to which reference is made for a complete statement of their provisions and contents. Certain words and terms used in this summary arc defined in the Aiiport Use Agreements and have the same meanings in this summary, except as defined otherwise in this Official Statement. The Airport Use Agreements signed by the Airline Parties are substantially similar except for provisions relating to different exclusive use premises for each Airline Party and the termination or extension of certain other agreements of each Airline Party relating to O'Hare.

Term
The Airport Use Agreements became effective in 1983 (or upon their execution if later), were amended and restated in 1985, were amended again in 1996 and 2005, and expire on May 11,2018.

Cos t-Revenue Centers
The Airport Use Agreements group areas in O'Hare for various accounting purposes into six Cost-Revenue Centers. These are the Terminal Area, the Airfield Area, the International Terminal Area, the Terminal Support Area, the Fueling System and the Land Support Area (see "Land Support Area" below for a separate discussion). The purpose of the Cost-Revenue Centers is to allow for the calculation of Airport Fees and Charges in a manner that allocates such fees and charges among the Airline Parties (and, in the case of the Airfield Area, among non-Airline Parties as well) based on their usage of O'Hare. Accordingly, each of the Cost-Revenue Centers (except the Land Support Area) has allocated to it Revenues, Operation and Maintenance Expenses, Debt Service and certain fund deposit requirements. Net deficits (that is, generally, the excess of Operation and Maintenance Expenses, Debt Service and fund deposits over Revenues) generated in any Fiscal Year in the Terminal Area and the Airfield Area Cost-Revenue Centers are paid by the Airline Parties in the form of Terminal Area Use Charges and Landing Fees, respectively. The net cost of the Fueling System Cost-Revenue Center is paid in the form of a separate Fueling System Fee. The Terminal Support Area and International Terminal Area Cost-Revenue Centers do not have specific fees or charges associated with them under the Airport Use Agreements. Instead, the net deficit (or net revenue) of each is calculated and then treated as a cost (or revenue) of the Terminal Area or the Airfield Area. It is not anticipated, however, that there will be a net deficit of the International Terminal Area under the Airport Use Agreements, because the net cost of the International Terminal Area is paid through fees and charges charged to the airlines that are signatories to the separate International Terminal Use Agreements.

Land Support Are a
The Land Support Area is a geographic portion of O'Hare that presently consists of vacant land, certain air rights and facilities, such as air cargo (including mail), freight forwarding, aircraft maintenance, flight kitchens and fuel storage, and a site at O'Hare formerly occupied by the U.S. Military. The expenses of the Land Support Area are not included in the calculation of Airport

C-1

Fees and Charges. Similarly, with certain exceptions, the income generated from facilities in the Land Support Area is not considered Revenues, and is not pledged as security for the payment of the Airport Obligations. There is currently no Debt Service allocated to the Land Support Area. One-half of the net revenues of the Land Support Area (excluding certain items) are deposited in the Revenue Fund for subsequent deposit in the Airport Development Fund described below under the subcaplion "Special bunds." In addition, any net revenues of the Land Support Area allocable to any car or vehicle rental concessions and Airport passenger public parking facilities located in the future on the former military site are to be deposited in the Revenue Fund and credited against Airport Fees and Charges.
Rentals, Fees and Charges ' ' ;
The Airport Use Agreements establish a $5 per square foot Terminal Area Rental for premises leased to Airline Parties for their exclusive occupancy. Terminal Area Use Charges for such premises also are calculated on a square footage basis.'Terminal Area Use Charges are based upon an allocation of all net costs attributable to the Terminal Area among Airline Parties leasing exclusive use premises in the Terminal Area.
,The net costs of the Fueling System Cost-Revenue Center are allocated among Airline
Parties on the basis of fuel gallonage. Each Airline .Party pays Fueling- System Fees on the basis
of a formula which reflects the ratio of its, total.gallonageto thcs total.gallonage. of all Airline
Parties., • . .-, ,.,, , , ... . ; , . .-:.,..<,.,• ... ¦ . . ,
' Landing Fees, are calculated by.'fjrst "deiermiiiing ,the Net Cost of the Airfield Area, .which
consists of portions of the following allocable fo^^ of'Operation and
Maintenance' Expense's j Debt Service, fund deposit requirements, and' net deficit of' the international Terminal Area, less the sum of Non-Use. Agreement Revenues ([exclusive of'landing fees payable' by persons other than Airline Parties)' and net revenues of the 'International Terminal j^rea^Ejeginning in,rates and charges year 2006, the Net Cost of the Airfield'Area is allocated among Airline Parties and users of the 'Airfield Area that are not Airline Parties on trie basis of the relative use of the Airfield Area by such persons. Such allocation of the Net Cost of the Airfield Area shall be based on the re^ectjye approved maximum'.'lahded weight '<$ aircraft, of Airline Parties landed'during such Fiscal Year and the approved maximum' landed weight of al 1 aircraft of other users during such Eiscal' Year', provided that for purposes of such allocation, the landed weight'df certain classes of users, of the Airfield Area maybe increasedby^ certain premium fart determined by the Commissioner of Aviation from time to time... Tq'the extent in ariy Fiscal Year Landing Fees collected from users of the Airfield Area other than Airline Parties are in excess, of the Net Cost of the Airfield Area al located to such users'for that Fiscal Year, such excess shall 'be applied in future years in a manlier that does hot, directly or indirectly, benefit any Airline Party.
General Commitment to Pay Airport Fees and Charges

The Airport Use Agreements provide that the, aggregate of all rentals, fees and charges to be paid under all Airport Use Agreements by all Airline Parties shall' be sufficient to pay for the net cost of operating, maintaining and developing O'Hare (excludirig the Land Support Area), including the satisfaction of all of the City's obligations' to make deposits and payments under any ordinance or resolution authorizing Airport-Obligations.' Airport'Fees and Charges hot paid by a
C-2

defaulting Airline Party, after appropriate collection efforts by the City and after exhaustion of certain funds available for that purpose, among others, are to be paid by all other Airline Parties as part of their Landing Fees as a result of the inclusion of such unpaid fees and charges in Operation and Maintenance Expenses of the Airfield Area.

Billing of Airport Fhes and Charges
Not later than 30 days prior to the end of each Fiscal Year, the City furnishes the Airline Parties a projection of the Landing Fee Rate and Terminal Area Use Charges for the next Fiscal Year {"Projection of Fees and Charges"). The Landing Fees, Terminal Area Use Charges and Fueling System Fees for the next Fiscal Year are computed on the basis of the Projection of Fees and Charges, and Terminal Area Rentals are based on leased exclusive use premises. Not later than the 10th day of each month the City bills each Airline Party for the amount of its allocable share of Terminal Area Rentals and Use Charges for the next month. The amount so billed is equal to 1/12th of each Airline Party's share of such rentals and charges for the Fiscal Year and is due on the first day of such next month. During each month the City also bills each Airline Party for Landing Fees payable for the preceding month; such Landing Fees are due within 30 days after the date of billing.
The Projection of Fees and Charges is adjusted at mid-year and Landing Fees, Terminal Area Use Charges and Fueling System Fees then may be adjusted accordingly. Within six months after the close of each Fiscal Year, a final audit is required to be prepared showing actual Landing Fees, Terminal Area Use Charges and Fueling System Fees for such Fiscal Year. Each Airline Party is entitled to a credit against subsequent billings (and in certain instances cash payments) for amounts paid in excess of the audited actual fees and charges, and is obligated to pay any deficiency along with its next monthly payment.

Capital Projects
The Airport Use Agreements contain as exhibits thereto descriptions of certain Capital Projects approved by the Airline Parties. The City was authorized in the Airport Use Agreements to issue Airport Obligations and include the Debt Service thereon in the calculation of Airport Fees and Charges without further consent or approval of the Airline Parties for all such Capital Projects, and also to (a) fund the cost of designing, constructing and equipping Capital Projects necessary to comply with any valid rule, regulation or order of any federal or state agency; (b) fund the cost of certain tenant improvements and certain relocation expenses; (c) fund insurance or condemnation award deficiencies; (d) refund or refinance Special Facility Revenue Bonds by agreement with Airline Parties; and (e) fund program and construction management costs and expenses rel ating to the implementation of the Airport Use Agreement.

America. Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are Tree from material, misstatement. ¦
An audit involves performing procedures to.obtain audi|,eyiidence,ab.qut the amounte.and disclosures, in. the financial statements. The procedures selected depend 6n the auditor's judgment, including the assessment of the risks of material misstatement of the financial statements, whether,due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to th.e;entity's preparation and fair presentat ion of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressingranopinipn.on the effectiveness of the entity's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates,, made by management, as well as evaluating the overall presentation of the financial statements.
We believe that the audit evidence we have bbtai'ned'is'sufficieht and appropriate to provide a basis for
our audit opinion. . .
Opinion : "li '

In our opinion, the basic financial statements 'referred to above present fairly,, iri all material respects,, the financial position of Chicago O'Hare International Airport as of December 31, 2015 and 2014, and the changes in its financial position, and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.
Emphasis of Matter
As discussed in Nolc 1 to the basic financial statements, the basic financial statements referred to above present only Chicago O'Hare International Aiiport, an enterprise fund of the City, and do not purport to, and do not, present the financial position of the City as of December 31, 2015 and 2014, changes in its financial position, or where applicable, its cash flows, in conformity with accounting principles generally accepted in the United States of America. Our opinion is not modified with respect to this matter.
As discussed in Notes 1 and 12 to the basic financial statements, beginning net position at January 1, 2015 was restated due to the City's adoption of Governmental Accounting Standards Board (GASB) Statement No. 68, Accounting and Financial Reporting for Pensions—an amendment of GASB Statement No. 27; and, ending net position as of December 31, 2015 reflects changes in certain benefits and actuarial assumptions (Note 7). Our opinion is not modified with respect to these matters.

Other Matters

Such information, although not a part of the basic financial statements, is required by the Governmental Accounting Standards Board who considers it to be an essential part of financial reporting for placing the basic financial statements in an appropriate operational, economic, or historical context. We have applied certain limited procedures to the required supplementary information in accordance with auditing standards generally accepted in the United States of America, which consisted of inquiries of management about the methods of preparing the information and comparing the information for consistency with management's responses to our inquiries, the basic financial statements, and other knowledge we obtained during our audit of the basic financial statements. * We do not express an opinion or provide any assurance on the information because the limited procedures do not provide us with sufficient evidence to express an opinion or provide any assurance.

MANAGEMENT'S DISCUSSION AND ANALYSIS (Dollars in thousands)


The following discussion and analysis of Chicago O'Hare International Airport's (the "Airport") financial performance provides an introduction and overview of the Airport's financial activities for the fiscal years ended December 31, 2015 and 2014. Please read this discussion in conjunction with the Airport's basic financial statements and the notes to basic financial statements immediately following this section.
FINANCIAL HIGHLIGHTS

Operating revenues for 2015 increased by $704 (0.0%) compared to prior-year operating revenues.
Operating expenses before depreciation and amortization increased by $310,703 (62.8%) compared to 2014 primarily due to increases in pension cost resulting from the implementation of GASB 68 and salaries and wages.
The Airport's total net position at December 31, 2015, was $474,600: This is a decrease of $985,484 (67.5%) over total net position at December 31, 2014 primarily due to the implementation of GASB 68, which established a net pension liability in 2015.
Capital asset additions for 2015 were $450,787 primarily due to buildings, runways and taxiway improvements and parking facilities upgrade.
2014
Operating revenues for 2014 increased by $126,844 (17.7%) compared to prior-year operating revenues.

-•—0per-a#Bg-ex-peiises-before-depreciation and amortization increased by $68,958 (16.2%)-compared-to— 2013 primarily due to increased salaries and wages, repairs and maintenance, and other operating. expenses.
The Airport's total net position at December 31, 2014, was $1,460,084. This is an increase of $132,685 (9.9%) over total net position at December 31, 2013.

• Capital asset additions for 2014 were $346,671 principally due to land acquisition, buildings, runways and taxiway improvements and roadway rehabilitation.
OVERVIEW OF THE BASIC FINANCIAL STATEMENTS
This discussion and analysis is intended to serve as an introduction to the Airport's basic financial statements. The Airport is included in the City's reporting entity as an enterprise fund. The Airport's basic financial statements comprise the basic financial statements and the notes to basic financial statements. In addition to the basic financial statements, this report also presents additional and statistical information after the notes to basic financial statements.
The Statements of Net Position present all of the Airport's assets and liabilities using the accrual basis of accounting. The difference between assets and deferred outflows and liabilities and deferred inflows is reported as Net Position. The increase or decrease in net position may serve as an indicator, over time, whether the Airport's financial position is improving or deteriorating. However, the consideration of other non-financial factors, such as changes within the airline industry, may be necessary in the assessment of overall financial position and health of the Airport.
The Statements of Revenues, Expenses and Changes in Net Position present all current fiscal year revenues and expenses, regardless of when cash is received or paid, and the ensuing change in Net Position.
The Statements of Cash Flows report how cash and cash equivalents were provided and used by the Airport's operating, capital financing, and noncapital financing and investing activities. These statements present the cash received and disbursed, the net increase or decrease in cash and cash equivalents for the year and the cash and cash equivalents balance at year-end.
The Notes to Basic Financial Statements are an integral part of the basic financial statements; accordingly, such disclosures are essential to a full understanding of the information provided in the basic financial statements.

In addition to the basic financial statements, this report includes Additional Supplemental Information and Statistical Information. The Additional Supplemental Information section presents the debt service coverage calculations, and the Statistical Information section includes certain unaudited information related to the Airport's historical financial and non-financial operating results and capital activities.
FINANCIAL ANALYSIS
Landing fees, terminal area use charges, and fueling system charges are assessed to the various airlines throughout each fiscal year based on estimated rates. Such rates are designed to yield collections from airlines adequate to cover certain expenses and required debt service and fund deposits as determined under provisions of the Amended and Restated Airport Use Agreement and Terminal Facilities Lease and the International Terminal Use Agreement and Facilities Lease ("Use Agreements"). Incremental amounts due from the airlines arise when amounts assessed, based on the estimated rates used during the year, are less than actual expenses and required deposits for the year. Such incremental amounts due from airlines are included in amounts to be billed. Incremental amounts due to the airlines arise when amounts assessed, based on the estimated rates used during the year, exceed actual expenses and required deposits for the year. Such incremental amounts due to airlines are included in billings over amounts earned.
At December 31, 2015, the Airport's financial position continued to be strong with total assets and deferred outflows of $10,447,148, total liabilities and deferred inflows of $9,972,548, and net position of $474,600.

The strong origin-destination passenger demand and the Airport's central geographical location near the center of the United States and along the most heavily traveled east/west air routes make the Airport a natural hub location.
United Airlines and American Airlines each use the Airport as one of their major hubs. United Airlines (including its regional affiliates) comprised 38.6% of the Airport's enplaned passengers in 2015 and 35.4% of the enplaned passengers in 2014.

Based on the Airport's rates and charges for fiscal year 2016, total budgeted operating and maintenance expenses are projected at $535,030 and total net debt service and fund deposit requirements are projected at $440,768. Additionally, 2016 nonsignatory revenues are budgeted for $390,907 resulting in a net airline requirement of $584,891 that will be funded through landing fees, terminal area use charges, and fuel system use charges.

NOTES TO BASIC FINANCIAL STATEMENTS
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2015 AND 2014


1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Organization—Chicago O'Hare International Airport (the "Airport") is operated by the City of Chicago Illinois (the "City") Department of Aviation. The Airport is included in the City's reporting entity as an enterprise fund. The City is a member of the Chicago-Gary Regional Airport Authority, which was created in 1995 to address the air transportation needs of the Chicago-Northwest Indiana Region.
Basis of Accounting and Measurement Focus—The accounting policies of the Airport are based upon accounting principles generally accepted in the United States of America, as prescribed by the Governmental Accounting Standards Board (GASB). The accounting and financial reporting treatment applied to a fund is determined by its measurement focus. The accounts of the Airport are reported using the flow of economic resources measurement focus.
The Airport uses the accrual basis of accounting, under which revenues are recognized when earned and expenses are recognized when incurred.
Annual Appropriated Budget—The Airport has a legally adopted annual budget, which is not required to be reported.
M anagement's Use of Estimates—The preparation of basic financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the basic financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from the estimates.
Cash, Cash Equivalents, and Investments—Cash, cash equivalents, and investments generally are held with the City treasurer as required by the Municipal Code of Chicago (the "Code"). Interest earned on pooled investments is allocated to participating funds based upon their average combined cash and investment balances. Due to contractual agreements or legal restrictions, the cash and investments of certain funds are segregated and earn and receive interest directly.
The Code permits deposits only to City Council-approved depositories, which must be regularly organized state or national banks and federal or state savings and loan associations, located within the City, whose deposits arc federally insured.
Investments authorized by the Code include interest-bearing general obligations of the City, the State of Illinois (the "State"), and the U.S. government; U.S. Treasury bills and other non-interest-bearing general obligations of the U.S. government purchased in the open market below lace value; domestic money market mutual funds regulated by and in good standing with the Securities and Exchange Commission; and tax anticipation warrants issued by the City. The City is prohibited by ordinance from investing in derivatives, as defined, without City Council approval.

The Airport values its investments at fair value or amortized cost as applicable. U.S. government securities purchased at a price other than par with a maturity of less than one year are reported at amortized cost. The fair value of U.S. agency securities, corporate bonds, and municipal bonds are estimated using recently executed transactions, market price quotations (where observable), or bond spreads.

Repurchase agreements can be purchased only from banks and certain other institutions authorized to do business in the State. The City treasurer requires that securities pledged to secure these agreements have a market value equal to the cost of the repurchase agreements plus accrued interest.
Investments, generally, dp not have a maturity in excess of 30 years from the date of purchase. Certain
other Investment balances are held, in accordance with the specific provisions of the applicable bond
ordinances.' '' ' _ ',"'," - ¦¦¦¦¦ •¦-

Deferred Inflows—Deferred inflows represent the differences between projected and actual actuarial experience related to pensions.
Net Position—Net position comprises the net earnings from operating and nonoperating revenues, expenses, and capital grants. Net position is displayed in three components—net investment in capital assets; restricted for debt service, capital projects, PFCs, airport use agreement and airport development fund, Cl'Cs, and other assets; and unrestricted. Net investment in capital assets consists of all capital assets, net of accumulated depreciation, and reduced by outstanding debt, net of debt service reserve and unspent proceeds. Restricted net position consists of net position on which constraints are placed by external parties (such as lenders and grantors), laws, regulations and enabling legislation. Unrestricted net position consists of all other net position not categorized as either of the above.
Employee Benefits—Employee benefits are granted for vacation and sick leave, workers' compensation, and health care. Specified unused vacation leave is accrued and may be carried over for one year. Sick leave is accumulated at the rate of one day for each month worked, up to a maximum of 200 days. Severance of employment terminates all rights to receive compensation for any unused sick leave. Sick leave pay is not accrued. Employee benefit claims outstanding, including claims incurred but not reported, arc estimated and recorded as liabilities. The Airport maintains insurance from a commercial carrier for workers' compensation claims. Settlements in each of the past two years have been less than insurance coverage maintained.
Employees are eligible to defer a portion of their salaries until future years under the City's deferred compensation plan created in accordance with Internal Revenue Code Section 457. The deferred compensation is not available to employees until termination, retirement, death, or unforeseeable emergency. The plan is administered by third-party administrators who maintain the investment portfolio. The plan's assets have been placed in trust accounts with the plan administrators for the exclusive benefit of participants and their beneficiaries and are not considered assets of the City.
The City is subject to the State of Illinois Unemployment Compensation Act and has elected the reimbursing employer option for providing unemployment insurance benefits for eligible former employees. Under this option, the City reimburses the State for claims paid by the State.
Bond Issuance Costs, and Bond Premiums, and Discounts—Bond issuance costs related to bond insurance and bond premiums and discounts are deferred and amortized over the term of the related debt. Other debt issuance costs are expenses in the period incurred.

Capital Grants—The Airport reports capital grants as revenue on the statements of revenues, expenses, and changes in net position. Capital grants are on a reimbursement basis and revenues are recognized when associated capital expenditures become eligible for grant reimbursement.
Noise Mitigation Costs—Funds expended for the noise mitigation program are recorded as nonoperating expenses in the period they are incurred.
Revenue Recognition—Landing fees, terminal area use charges, and fueling system charges are assessed to the various airlines throughout each fiscal year based on estimated rates. Such rates are designed to yield collections from airlines adequate to cover certain expenses and required debt service and fund deposits as determined under provisions of the Amended and Restated Airport Use Agreement

and Terminal Facilities Lease and the International Terminal Use Agreement and Facilities Lease ("Use Agreements"), incremental amounts due from the airlines arise when amounts assessed, based on the estimated rates used during the year, are less than actual expenses and required deposits for the year. Such incremental amounts due from airlines are included in amounts to be billed. Incremental amounts due to the airlines arise when amounts assessed, based on the estimated rates used during the year, exceed actual expenses and required deposits for the year. Such incremental amounts due to airlines are included in billings over amounts earned.

Passenger Facility Charge Revenue—The Airport imposed PFCs of $4.50 per eligible enplaned passenger for.the years.ended:December 31, 20.15 and 2014, respectively. PFCs are available, subject to Federal Aviation Administration regulation and approval, to finance specific eligible capital projects.

Customer Facility .Charge Revenue—The Airport imposed a CFC of $8.00 per contract day on each customer for motorvehicle rentals at the Airport beginning August 1, 2010. CFCs are available to finance specific eligible capital projects. The City reports CFC revenue as nonoperating revenue and relatedinoncapitafcxpenses as nonoperating expenses in conformity with industry practice.

Custodial Credit Risk—Cash and Certificates of Deposit—This is the risk that in the event of a bank failure, the City's Deposits may not be returned. The City's Investment Policy states that in order to protect the City public fund deposits, depository institutions are to maintain collateral pledges on City deposits and certificates of deposit during the term of the deposit.
For certificates of deposit of banks or savings and loan associations designated as municipal depositories which are insured by federal deposit insurance, any amount of the deposit in excess of the federal deposit insurance shall be either: (1) fully collateralized at least 102 percent by: (i) marketable U.S. government securities marked to market at least monthly; (ii) bonds, notes, or other securities constituting the direct and general obligation of any agency or instrumentality of the United States; or (iii) bonds, notes orother securities constituting a direct and general obligation of any county, township, city, village, incorporated town, municipal corporation, or school district, of the State of Illinois or of , any other state, or of any political subdivision or agency of the State of Illinois or any other state which are rated in either the AAA or AA rating categories by at least two accredited ratings agencies and maintaining such rating during the term of such investments; (2) secured by a corporate,surety bond issued by an insurance company licensed to do business in Illinois and having a claims-paying rating in the top rating category as rated by a nationally recognized statistical rating organization and maintaining such rating during the term of such investment; or (3) fully collateralized at least 102 percent by an irrevocable letter of credit issued in favor of the City of Chicago by the Federal Home Loan Bank, provided that the Federal Home Loan Bank's short-term debt obligations are rated,in the highest rating category by at least one accredited ratings agency throughout the term of the certificate of deposit.
The collateral required to secure City funds must be held in safekeeping and pursuant to collateral agreements which would prohibit release or substitution of pledged assets without proper written notification and authorization of the City Treasurer. The final maturity of acceptable collateral pledged shall not exceed 120 months.
The bank balance of cash and certificates of deposit with the City's various municipal depositories was $626.6 million as of December 31, 2015. Of the bank balance, 98.3% was either insured or collateralized with securities held by City agents in the City's name. An amount of $10.5 million was uncollateralized at December 31, 2015, and thus was subject to custodial credit risk.

PENSION PLANS
'General Information about the Pension Plan :>
:«. - - Plan Description. Retirement Benefit—Eligible O'Hare Fund-employees participate in one of four
single=employer defmed-benefit pension-plans (Plans)7~Thesc Plans are: the Municipal
Employees'(Municipal); the Laborers'(Laborers') and Retirement Board-Employees';' the Policemen's ''' (Policemen's); and the Firemen's (Firemen's) Annuity and Benefit Funds of Ghicagd^Plaris are .^administered by individual retirement boards of trustees'' comprised of City officials or their'designees and of trustees elected by plan members. Each Plan issues a publicly available financial report that .... includes financial statements and required supplementary: informabon. that.can be: obtained at
www.meabf.brg ., www.labfchicago.org , www.chipabf.org and www.fabf.orgg .
Benefits Provided—The Plans provide retirement, disability, and death benefits as established by State law. Benefits generally vest after 10 years of credited service.' Employees.qualify for an-unreduced retirement age minimum formula annuity based on a combination of years of service and age of retirement. Employees may also receive a reduced retirement age minimum formula annuity if they do not meet the age and service requirements for the unreduced retirement age annuity. The requirement of age and service are different for employees who became members before January 1, 2011, and those who became members on or after January 1, 2011. The annuity is computed by multiplying the final average salary by a percentage ranging from 2.2 percent to 2.5 percent per year of credited service. The final average salary is the employee's highest average annual salary for any four consecutive years within the last 10 years of credited service for participants who became members before January 1, 2011 and any eight consecutive years within the last 10 years of credited service for participants who became members on or after January 1,2011.


-35 -

Benefit terms provide for annual adjustments to each employee's retirement allowance subsequent to the employees' retirement date. For participants who became members before January 1,2011, the annual adjustments for Municipal and Laborers are 3.0 percent, compounded, and for Firemen's and Policemen's 3.0 percent, simple, for annuitants born before 1955 and 1.5 percent, simple, born in 1955 or later. For participants that first became members on or after January 1, 201 1, the annual adjustments are equal to the lesser of 3.0 percent and 50 percent of CPI-U of the original benefit.
Contributions—Historically, State law required City contributions at statutorily, not actuarially, determined rates. State law also requires covered employees to contribute a percentage of their salaries. The City's contribution was calculated based on the total amount of contributions by employees to the Plan made in the calendar year two years prior, multiplied by 1.25 for the Municipal, 1.00 for (he Laborers', 2.00 for the Policemen's, and 2.26 for the Firemen's. The City's contributions are budgeted in the same year as the applicable levy year for the property taxes funding the contributions. The City's contributions are then paid to the pension funds in the following year (which is when the levied property taxes are collected and paid to the City by the Cook County Treasurer).
State law in effect at December 31, 2015 for the Policemen's and Firemen's Plans, known as Public Act 96-1495 (P.A. 96-1495), requires the City to significantly increase contributions lo those Plans beginning in 2015. In each year, the City must contribute the amount needed for each Plan to achieve a 90% Funded Ratio by the end of 2040.
Public Act 99-0506 (P.A. 99-0506) was enacted on May 31, 2016. P.A. 99-0506 changed the funding requirements required by Public Act 96-1495, providing that the City make a fixed contribution amount for 2015 through 2019:which is significantly larger than contributions made prior to the adoption of P.A. 96-1495 but smaller than the contributions required under P.A. 96-1495. P.A. 99-0506 requires that the City's contributions arc at actuarially determined rates beginning in 2020 and future funding be sufficient to produce a funding level of 90% by the year ended December 31, 2055 (instead of 2040 required by P.A. 96-1495). As this law was enacted subsequent to December 31, 2015, the measurement of the City's net pension liability as of December 31, 2015, was not impacted, since the liability was measured using the law in effect as of December 31, 2015. The City will be taking into consideration the impact of this new law when measuring the liability in 2016. The new law is expected to increase the City's net pension liability. .
The City's contributions to Municipal and Laborer's are determined pursuant to the formulas set forth in the Illinois Pension Code (the Pension Code). Pursuant to Public Act 098-641 (P.A. 98-641), the City's contributions to Municipal and Laborer's were scheduled to increase beginning in 2015; however, in July 2015 the Circuit Court of Cook County determined P.A. 98-641 to be unconstitutional. As a result of such determination by the court, the provisions of the Pension Code governing the City's contributions to MEABF and LABF have reverted to the provisions in effect prior to the enactment of P.A. 98-641. Furthermore, in March 2016, the Illinois Supreme Court upheld the ruling made by the Circuit Court.

The contribution to all four pension plans from the Airport was $25.8 million for the year ended December 31, 2015.
Pension Liabilities, Pension Expense, and Deferred Outflows of Resources and Deferred Inflows of Resources Related to Pensions
At December 31, 2015, the Airport reported a liability of $1,542 million for its proportionate share of the net pension liability. The net pension liability was measured as of December 31, 2015, and the total pension liability used to calculate the net pension liability was determined by an actuarial valuation as of


-36-
that date. The Aiiport's proportion of the net pension liability was determined based on budgeted Aiiport salaries within each corresponding pension plan. At December 31, 2015, the Airport's proportion was 5.8 percent of the Municipal Plan, 6.2 percent of the Laborer's Plan, 1.3 percent of the Policemen's Plan and 4.9 percent of the Firemen's Plan.

Changes in Benefits and Actuarial Assumptions: As discussed above, P.A. 98-0641 was determined to be unconstitutional resulting in changes in the discount rate caused by a change in the required funding policy and changes in benefits for the participants of the Municipal and Laborers pension plans, which include restoring full automatic annual increase and changes in the retirement age for certain
participants.

The.-change;in the.discpunt rate assumption increased the Airports allocated net pension liability by $507.3.million for.Muni'cipa'l and $73.1 million for Laborers'. This impact.is being amortized over a five year period for.Munieipal and a four year period for Laborers'. The change in benefits increased the Airport's allocated share of the net pension liability by $124:6 million for.Munieipal and $23.9 million for Laborers'. This impact is recognized as a portion of 2015 pension expense in its entirety. For the year ended,Dccember;31, 2015,--the Airport recognized pension expense of,$339.5 million.

At December 31, 2015, the Airport reported deferred outflows of resources of $487.9 million and deferred inflows of resources of $8.6 million related to pensions from the following sources:

The long term expected rate of return on pension plan investments was determined using the building-block method in which best-estimate ranges of expected future real rates of return (expected returns, net of pension plan investment expense and inflation) are developed for each major asset class. These ranges are combined to produce the long-term expected rate of return by weighting the expected future real rates of return by the target asset allocation percentage and by adding expected inflation. The target allocation and best estimates of arithmetic real rates of return for each major asset class arc summarized in the following table:

Discount Rate
Municipal—The discount rate used to measure the total pension liability was 3.73%. This Single Discount Rate was.based on an expected rate of return on pension plan investments of 7.5 percent and a municipal bond rate of 3.6 percent (based on the Bond Buyer 20- Bond Index of general obligation municipal bonds as of December 31, 2015).The projection of cash flows used to determine the discount rate, assumed member contributions will be made at the current contribution rate and that employer contributions will be made at the 1.25 multiple of member contributions from two years prior. For this purpose, only employer contributions that are intended to fund benefits of current plan members and their beneficiaries are included. Projected employer contributions and contributions from future plan members that are intended to fund the service costs of future plan members and their beneficiaries are not included: Based on those assumptions, the pension plan's fiduciary net position was not projected to be available to make all projected future benefit payments of current plan members. The projected benefit payments through 2023 were discounted at the expected long-term rate of return. Starting in 2024, the projected benefit payments were discounted at the municipal bond fate. Therefore; a single equivalent, blended discount rate of 3.73% was calculated using the long-term expected rate of return and the municipal bond index.
Laborers'—A Single Discount Rate of 4.04 percent was used to measure the total pension liability. This Single Discount Rate was based on an expected rate of return on pension plan investments of 7.5 percent and a municipal bond rate of 3.6 percent (based on the Bond Buyer 20- Bond Index of general obligation municipal bonds as of December 31, 2015).The projection of cash flows used to determine this Single Discount Rate assumed that plan member contributions will be made at the current contribution rate and


-40 -

that employer contributions will be made at rates equal lo the difference between statutory contribution rates and the member rate. Based on these assumptions, the pension.plan's fiduciary net position and future contributions were sufficient lo finance the benefit payments through the year 2027. As a result, the long-term expected rate of return on pension plan investments was applied to projected benefit payments through the year 2027, and the municipal bond rate was applied to all benefit payments after that date.
Policemen's—A Single Discount Rate of 7.15 percent was used to measure the total pension liability. This Single Discount Rate was based on an expected rate .of return on.pension plan investments of 7.5 percent and a municipal bond rate of 3.6 .percent (based on the Bond Buyer 20- Bpnd.Index of general obligation municipal bonds as of December 31, 2015).The projection of cash flows used to determine this Single Discount Rate assumed that plan member contributions will be, made at the current contribution rate and that employer contributions will be made at rates equal to the difference between statutory contribution rates and the member rate. Based on these assumptions, the pension plan's fiduciary net position and future contributions were sufficient to finance the benefit payments through ' the year 2063. As a result, the long-term expected rate of return on pension plan investments was applied to projected benefit payments through the year 2063, and the municipal bond rate was applied to all benefit payments after that date.

Firemen's—A Single Discount Rate of 7.16 percent was'used to measure the total pension-liability. This Single Discount Rate was based on an expected rate bf.return on pension plan in vestments.of 7.5 percent and a municipal bond rate of 3.6 percent (based on the Bond Buyer 20- Bond Index of general obligation municipal bonds as of December 31, 2015).Thc projection of cash flows used to determine this Single Discount Rate assumed that member contributions will be made at the current contribution rate and that employer contributions will be made at rates' equal to the difference between statutory contribution rates and the member rate. Based on these assumptions, the Plan's fiduciary net position and future contributions were sufficient to finance fumrc-benefit payments only-through the year 206T."As a result, the long-term expected rate of return on pension plan investments was applied to projected benefit payments through the year 2061, and the municipal bond rate was applied to all benefit payments after that date.

Actuarial Method and Assumptions—For the Pension Funds' subsidies, the actuarial valuation forth fiscal year ended December 31, 2015 was determined using the Entry Age Normal actuarial cost method. Projections of benefits for financial reporting purposes are based on the substantive plan (the plan understood by the employer and plan members) and included the types of benefits provided at the time of each valuation and the historical pattern of sharing of benefit costs between the employer and plan members to that point. The actuarial method and assumptions used include techniques that are designed to reduce the effects of short term volatility in actuarial accrued liabilities and the actuarial value of assets, consistent with the long term perspective of the calculations.

Other PostEmployment Benefits—City Obligation
Up to June 30, 2013, the annuitants who retired prior to July 1, 2005 received a 55 percent subsidy from the City and the annuitants who retired on or after July 1, 2005 received a 50, 45, 40 and zero percent subsidy from the City based on the annuitant's length of actual employment with the City for the gross cost of retiree health care under a court approved settlement agreement, known as the "Settlement Plan." The pension funds contributed their subsidies of $65 per month for each Medicare eligible annuitant and $95 per month for each Non-Medicare eligible annuitant to their gross cost. The annuitants contributed a total of $104.4 million in 2015 to the gross cost of their retiree health care pursuant to premium amounts set forth in the below-referenced settlement agreement.
The City subsidized a portion of the cost (based upon service) for hospital and medical coverage for eligible retired employees and their dependents based upon a settlement agreement entered in 2003 and which expired on June 30, 2013.
On May 15, 2013, the City announced plans to, among other things: (i) provide a lifetime healthcare plan to former employees who retired before August 23, 1989 with a contribution from the City of up to 55% of the cost of that plan; and (ii) beginning July 1, 2013, provide employees who retired on or after August 23, 1989 with healthcare benefits in a new Retiree Health Plan (Health Plan), but with significant changes to the terms including increases in premiums and deductibles, reduced benefits and the phase-out of the Health Plan for such employees by December 31, 2016.
The cost of health benefits is recognized as an expenditure in the accompanying financial statements as claims are reported and are funded on a pay-as-you-go basis. In 2015, the net expense to the City for providing these benefits to approximately 22,697 annuitants plus their dependents was approximately $44 million.

Plan Description Summary—The City of Chicago was party to a written legal settlement agreement outlining the provisions of the Settlement Plans, which ended June 30, 2013. The Health Plan provides for annual modifications to the City's level of subsidy. It is set to phase.out over three years, at which the Health Plan, along with any further City subsidy, will expire by December 31, 2016, for all but the group of former employees (the Kbrshak class of members) who retired before August 23, 1989, who shall have lifetime benefits. Duty Disabled retirees who have statutory pre-63/65 coverage will continue to have fully subsidized coverage under the active health plan until age 65.
The provisions of the Health Plan provide in general, that the City pay a percentage of the cost (based upon an employee's service) for hospital and medical coverage to eligible retired employees and their dependents for the specified period, ending December 31, 2016. The percentage subsidies were revised to reduce by approximately 25 percent of 2013 subsidy levels in 2014 and 50 percent of 2013 subsidy levels in 2015, and 75 percent of 2013 subsidy levels in 2016.

In addition, State law authorizes the four respective Pension Funds (Policemen's, Firemen's, Municipal Employees', and Laborers') to provide a fixed monthly dollar subsidy to each annuitant who has elected coverage under any City health plan through December 31, 2016. After that date, no Pension Fund subsidies are authorized. The liabilities for the monthly dollar Pension Fund subsidies contributed on behalf of annuitants enrolled in the medical plan by their respective Pension Funds are included in the Net Pension Obligation ("NPO") actuarial valuation reports of the respective four Pension Funds under GASB 43.
Special Benefits under the Collective Bargaining Agreements (CBA)—Under the terms of the collective bargaining agreements for the Fraternal Order of Police (FOP) and the International


-46-

Association of Fire Fighters (IAFF). certain employees who retire after attaining age 55 with the required years of service are permitted to enroll themselves and their dependents in the healthcare benefit program offered to actively employed members. They may keep this coverage until they reach the age of Medicare eligibility. These retirees do not contribute towards the cost of coverage, but the Policemen's Fund contributes S95 per month towards coverage for police officers; the Firemen's Fund does not contribute.
Both of these agreements which provide pre-65 coverage originally expired at June 30, 2012. These
benefits have been renegotiated to continue through 2016 or June 30, 2017, depending on bargaining
unit agreements. This valuation assumes that the CBA .special benefits, except for .those who will have
already retired as of December 3 1, 2016, will cease on December 31, 2016 or June 30, 2017, depending
on bargaining.unit agreements. • :¦¦ l ¦ -,

Funding Policy—No assets are accumulated or dedicated to funding the retiree health plan benefits.

Annual OPEB Cost and Net OPEB Obligation—The City's annual other post-employmenttbcncfit (OPEB) cost (expense) is calculated based on the annual required contribution of the employer (ARC). The, ARC (Annual Required Contribution) represents; a level of funding;that; if paid on an. ongoing basis, is projectedrtoicover the normal-cost each year,and to amortize any. unfunded actuarial liabilities over a period of ten years. i,:

Funded Status and Funding .Progress—As of January 1, 2015, the most recent actuarial valuation date, the actuarial accrued liability for benefits was $780.6 million all of which was unfunded. The covered payroll (annual payroll of active employees covered by the plan) was approximately $2,488.0 million and the ratio of the unfunded actuarial accrued liability to the covered payroll was 31.4 percent:

Actuarial valuations of an ongoing plan involve estimates of the value of reported amounts and assumptions about the probability of occurrence of events far into the future. Examples include assumptions about future employment, mortality, and the healthcare cost trend. Amounts determined regarding the funded status of the plan and the annual required contributions of the employer are subject to continual revisions as the results are compared with past expectations and new estimates are made about the future. The schedule of funding progress, presents, as required, supplementary information following the notes to the financial statements (dollars in thousands, unaudited).

For the Health Plan benefits (not-provided by the Pension Funds), the entry age normal actuarial cost method was used. The actuarial assumptions included an annual healthcare cost trend rate of 8.0% initially, reduced by decrements to an ultimate rate of 5.0% in 2026. The range of rates included a 3.0% inflation assumption. Rates included a 2.5% inflation assumption. The plan has not accumulated assets and does not hold assets in a segregated trust. However, the funds expected to be used to pay benefits are assumed to be invested for durations which will yield an annual return rate of 3.0%. The remaining Unfunded Accrued Actuarial Liability is being amortized as a level dollar amount over ten years. The benefits include the provisions under the new Health Plan, which will be completely phased-out by December 31, 2016, except for the Korshak category, which is entitled to lifetime benefits. Also included in the Non-CBA benefits are the duty disability benefits under the active health plan payable to age 63/65.

For the Special Benefits under the CBA for Police and Fire, the renewed contracts" expiration dates of June 30, 2016 (for Police Captains, Sergeants and Lieutenants) and June 30, 2017 for all other Police and Fire are reflected, such that liabilities are included only for payments beyond the end of the calendar year of contract expiration on behalf of early retirees already retired and in pay status as of December 31 of the expiration year of the contract. The entry age normal method was selected. The actuarial assumptions included an annual healthcare cost trend rate of 8.0% in 2014, reduced by decrements to an ultimate rate of 5.0% in 2026. Rates included a 2.5% inflation assumption. The plan has not accumulated assets and does not hold assets in a segregated trust.

Included in operating expenses are reimbursements to the general fund of the City for services provided by other City departments, employee fringe benefits, and certain payments made on behalf of the Airport. Such reimbursements amounted to $86.1 million and $72.8 million in 2015 and 2014, respectively.

10. COMMITMENTS AND CONTINGENCIES
The Airport has certain contingent liabilities resulting from litigation, claims, and commitments incident to its ordinary course of business; Management expects that the final resolution of these contingencies will not have a material adverse effect on the financial position or results of operations of the Airport.
The Airport provides employee health benefits under a self-insurance program, administered by the City. Such claims outstanding, including claims incurred but not reported, are estimated and recorded as liabilities in the basic financial statements.

Dear Ms. Evans:

This Letter of the Airport Consultant (Letter) serves to reaffirm the findings from the Report of the Airport Consultant (2016 Report), dated November 18, 2016, with consideration of information made available since the 2016 Report. The 2016 Report was prepared in connection with the issuance of the Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2016 A, B, and C (the 2016 Refunding Bonds) and Chicago O'Hare International Airport General Airport Senior Lien Revenue Bonds, Series 2016 D, E, F, and G (the 2016 New Money Bonds, and, together with the 2016 Refunding Bonds, are referred to as the 2016 Bonds).

The 2016 Report set forth the findings, assumptions, and projections related to the air traffic and financial analyses developed by Ricondo & Associates, Inc. (R&A) in conjunction with the issuance of the 2016 Bonds by the City of Chicago (the City), which owns and operates Chicago O'Hare International Airport (the Airport). This Letter, based on the findings of the 2016 Report and the updated information in connection with the City's planned issuance of its Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2017 A, B, and C (2017 Refunding Bonds) and Chicago O'Hare International Airport General Airport Senior Lien Revenue Bonds, Series 2017 D (2017 New Money Bonds, and together with the 2017 Refunding Bonds, the 2017 Bonds) contained herein, serves to reaffirm the overall conclusions R&A made in the 2016 Report regarding the City's ability to comply with the Rate Covenants established in the Senior Lien Indenture, and the reasonableness of the resulting projected airline costs.

The 2017 Bonds

The 2017 Bonds will be issued pursuant to an ordinance adopted by the Chicago City Council on September 14, 2016 (the Bond Ordinance) and the Master Indenture of Trust securing Chicago O'Hare International Airport General Airport Revenue Senior Lien Obligations dated as of September 1, 2012 (the

Purpose of This Letter of the Airport Consultant

R&A prepared the 2016 Report for the stated purposes as expressly set forth in the 2016 Report and for the sole use of the City and its intended recipients. The techniques and methodologies used in preparing the 2016 Report were consistent with industry practices at the time of preparation and the 2016 Report should be read in its entirety for an understanding of the analysis, assumptions, and opinions presented. The 2016 Report was included as Appendix E in each of the Official Statements for the issuance of the 2016 Bonds. It is attached to this Letter for reference as Attachment 2.2 The 2016 Report incorporated projections of debt service associated with the 2016 Bonds and future General Airport Revenue Bonds (GARBs) anticipated by the City to be issued during the Projection Period.
This Letter provides updated information that has become available since the 2016 Report was prepared, including information regarding the 2017 Bonds, as well as updated data regarding ongoing and future Airport capital projects, the economic base for air transportation at the Airport, air traffic at the Airport, and Airport financial operations including actual Series 2016 Bonds debt service and anticipated debt service on the 2017 New Money Bonds.
On the basis of the updated analysis set forth in this Letter, R&A reaffirms its opinion that the Revenues and in some cases Other Available Moneys generated each year of the Projection Period are expected to be sufficient to comply with the Rate Covenants established in the Senior Lien Indenture and that the resulting projected airline costs should remain reasonable.
Table 3 summarizes key updates and findings by subject matter since the 2016 Report that support this conclusion.











Attachment 1 is provided directly following the updated financial analysis in this Letter and consists of updated financia projections tables consistent with Appendix B of the 2016 Report.

Expansion, which are anticipated to be funded using proceeds from the 2017 New Money Bonds. The Terminal 5 Expansion includes the expansion of and modifications to Terminal 5, the International Terminal, to accommodate increased traffic at the Airport. Additional information on the 2017 Airport Projects is provided in the 2017 Airport Projects section of this Letter. Majority-In-Interest (Mil) approvals for the 2017 Airport Projects have been received from the airlines serving the Airport.
Proceeds from future GARBs are needed to fully fund the Airport 2017-2021 CIP. For purposes of the financial analysis in this Letter, it is assumed that GARBs will be issued in 2018 to fund $1.19 billion of costs of the 2017-2021 CIP projects.
Other Recently Announced Capital Programs
The Concourse L Extension scope remains unchanged from section 2.2.3.1 of the 2016 Report. The project is under construction and anticipated to be completed in 2018. It is being funded directly by American Airlines.
The Hotel Development described in section 2.2.3.2 of the 2016 Report is ongoing and the City is still pursuing the construction of two new hotels and the modernization of the existing terminal hotel. The Request for Proposal process is underway for the modernization of the existing terminal hotel and for a new hotel located near Terminal 5. The total investment for the three development projects is estimated to be approximately $350 million, planned to be funded by a special facility loan backed by hotel revenues, and construction is expected to be complete between 2020 and 2022. No future GARBs associated with the hotel development are included in the financial analysis in this Letter.
The TAP, a long-term terminal development and redevelopment of the Airport's terminal core described in section 2.2.3.4 of the 2016 Report, remains in the planning stages with the City and airline representatives collectively evaluating terminal development and phasing options. Current plans continue to include the redevelopment of Terminal 2 into a new central terminal and gate expansion west of the existing terminal core. While funding for the TAP is anticipated to include the proceeds of future bonds with potential debt service payable during the Projection Period, due to the continued uncertainty of timing and project costs, the updated financial analysis contained in this Letter does not include any debt service payments associated with the TAP. The TAP should be noted as an upcoming program that is expected to be implemented in phases and have a material cost. It is anticipated to enable long-term airline growth and to alleviate the need for certain future capital projects that could be necessary in order to maintain the existing facilities at the Airport if the TAP were not pursued.

The updated financial analysis presented in this Letter assumes that approximately $1.19 billion of 2017-2021 CIP project costs not already funded from existing sources or the 2017 New Money Bonds will be funded through future GARB issuances, as described below.

2017 AIRPORT PROJECTS
The 2017 Airport Projects include the projects comprising the Terminal 5 Expansion and are anticipated to be funded, with proceeds from the 2017 New Money Bonds.
Terminal 5 Expansion
The City is undertaking an expansion and set of modifications to Terminal 5 to accommodate increased traffic and .increased aircraft size at the Airport. The Terminal 5 Expansion increases both the number of gates (from 19 to 28) and the size of gates at Terminal 5. The project includes an extension of the east concourse of Terminal 5, which includes the addition of approximately 279,000 square feet of gross floor area; the addition of 9 aircraft parking positions and installation of associated passenger loading bridges; and the extension of sterile corridors feeding the FIS facility. The project also includes the expansion of the existing terminal apron by approximately 1.5 million square feet, increasing total linear feet of gate frontage by approximately 25 percent.
The Terminal 5 Expansion also includes the reconfiguration of gates on the west concourse of Terminal 5. Gates Ml through M6 are anticipated to be modified to accommodate eight narrowbody aircraft which includes the modification of existing passenger loading bridges and the addition of new passenger loading bridges. Existing Terminal 5 facilities are anticipated to be modified to accommodate additional activity. Modifications to systems include the expansion of the security screening checkpoint; the modification of the baggage system, ticket counter lobby facilities, and FIS inspection areas; and other projects.

There have been no material changes to the scope of this project since the 2016 Report;'however, the funding plan for this'project'has changed. Iri the 2016 Report/the $266.8 million' Terminal 5 Expansibrr was 'ahticipated'to 'be 'funded through a'combihatibri of PFC revenue oh a pay-'as-ybu-gblasts' and :'PFC Revenue' Bonds ($188.6 million), with the-remaining'funding ($78:2 million) tb come from Airport discretionary funds. :'
The City has received PFC authority from the FAA to use PFCs on the Terminal 5 Expansion project and may elect to apply PFC Revenue to offset portions of the debt service on the 2017 New Money Bonds, however, there is no pledge of PFC Revenues to the 2017 New Money Bonds and the updated financial analysis in this Letter does not assume PFC Revenue is applied to the 2017 New Money Bonds.
The 2017 Airport Projects have received Majority-In-Interest approval from the airlines. For purposes of the updated financial analysis, it is assumed that $266.8 million of 2017 Airport Project costs will be funded with the 2017 New Money Bonds. However, if this amount is not funded with the 2017 New Money Bonds, then the unfunded project amounts are anticipated to be funded with proceeds from

Updated Information Regarding the Economic Base for Air Transportation

R&A conducted a review of certain socioeconomic information made available since the date of the 2016 Report. The information suggests that the findings regarding the Airport's Air Trade Area (the Chicago-Naperville-Joliet Metropolitan Statistical Area [MSA] and the Kankakee-Bradley MSA)3 and economic base for air transportation remain valid. The economic base of the Air Trade Area remains capable of supporting increases in demand for air transportation at the Airport during the Projection Period. A brief discussion of recent unemployment and economic data, updated Woods & Poole Economics, Inc. (Woods & Poole) projections, and survey data from the National Association for Business Economics (NABE) is provided below.
The Air Trade Area is well-positioned because of its broad and diverse economic base. It is affected by overall economic conditions in the U.S. Economic activity in the U.S. continues to expand at a moderate pace. The 2016 Report presented the most current (September 2016) forecast published by business economists from the NABE, which indicated consensus for real gross domestic product (GDP) growth of 1.5 percent in 2016 and 2.3 percent in 2017.4 Actual real GDP growth in 2016 was 1.6 percent5, higher than what had been forecasted in September 2016, and in the most recently published NABE survey (March 2017), the median forecast for real GDP growth in 2017 remains unchanged at 2.3 percent.6 Those surveyed predict a median forecast for real GDP growth of 2.5 percent in 2018.
As presented in the 2016 Report, data from Woods & Poole projected the Air Trade Area's gross regional product (GRP) to increase at a compound annual growth rate (CAGR) of 2.0 percent through the

Projection Period, from $615.95 billion in 2015 to $749.82' billion in 2025. During the same period, data from Woods and Poole projected the U.S. GDP to increase at a GAGR-of'2:2- percent, -from $17.9 trillion in 2015 to $22.3 trillion in 2025. The updated Woods & Poole projections suggest slightly lower long-term growth, with a projected CAGR of 1.8 percent for the Air Trade Area's GRP during the Projection Period (increasing from $643.30 billion in 2016 to $758.05 billion in 2025). The U.S. GDP is now projected to increase at a ¦CAGR:of 2:l.: percent.over the same period (increasing;from"$-l!8.5 trillion; to $22-.4: trillion). Despite slower projections of Air Trade Area GRP and U.S. GDP growth through 2025, because actual Air Trade Area GRP and U.S. GDP data for 2015 and 2016 were higher than previously estimated by Woods & Poole, projections for both Air Trade Area GRP and U.S. GDP levels are above what had been previously projected - in ,the 2016-.Report (i.e. the. Air Jrade-Area's GRP was .projected $758.05,billion).
In March 2017 (latest data available.at the time, of this Letter), the unemployment rate for the Air Trade Area reported by the U.SDepartment of Commerce, Bureau of Labor Statistics was 4.15 percent (non-seasopally adjusted)8, lower.than the rate, for the nation (4.6 p^rjcent,. nqn-se.aspnaNy adjusted). The Air Trade Area's unemployment rate, in March 2017. was lower than it was in March 2016 (6.3 percent in March 20i6, non-seasonally adjusted), and this 1.8 percentage point improvement exceeds the employment recovery in the nation. In comparison, the national unemployment rate improved by 0.5 percentage points, from 5.1 percent (non-seasonally adjusted) in March 2016. The NABE survey cited in the.2016-Report estimated that the average annual U.S. unemployment rate would be 4,8 percent in.2016 and;,4.6:percent in 2017...The actual, annual U.S. unemployment rate .was, 4.9 percentdn 2016,,,-and .the forecast for 2017 remained unchanged in the.March 2017 survey.

176,000jobs per month.11 Slower employment growth is expected in the short term, with a median employment growth forecast from the March 2017 NABE survey of 183,000 jobs per month in 2017 and 166,000 jobs per month in 2018.
Based on the analysis described in Chapter 3 of the 2016 Report, as well as the most recent unemployment data and economic forecast information noted above, R&A's opinion is unchanged: the Air Trade Area's economic base remains broad and diversified, and will continue to support long-term growth in demand for air transportation services at the Airport. R&A's review of the most recent economic data and information suggests that the economic projections used to develop the traffic forecast presented in the 2016 Report remain valid.

Updated Information Regarding Air Traffic

Based on a review of actual air traffic activity at the Airport, air service trends, and published future seat capacity data that has become available since the 2016 Report, R&A is of the opinion that the air traffic activity projections presented in the 2016 Report (see Chapter 4, "Air Traffic," of the 2016 Report) remain reasonable and are therefore unchanged at the time of this Letter.
The activity projections developed for the 2016 Report were based on a number of underlying assumptions (see sections 4.4, 4.5, and 4.6 of the 2016 Report). Notable recent air service developments that support these assumptions, and the projections contained within the 2016 Report are described below. In 2016, the Chicago Department of Aviation (CDA) reported 38,858,080 enplaned passengers at the Airport, a growth of 1.2 percent from 2015. This total exceeds the 2016 enplaned passengers forecast in the 2016 Report of 38,524,287, or 0.4 percent forecast growth from 2015. Passenger activity growth has been driven primarily by domestic O&D and international passengers. Domestic passenger volumes increased 0.6 percent while international passenger volumes increased 5.7 percent. During the four quarters ended Q3 201612 O&D passenger volumes increased to 21.0 million enplaned passengers from 20.1 million enplaned passengers in CY 2015, a growth of 4.5 percent. Through March 2017, enplaned passengers have increased 0.4 percent compared with the same period in 2016.

In the near-term, total scheduled seat capacity at the Airport is projected to increase approximately 2:8 percent in i2017o'This rgrowth, is being supported', by-, many carriers :at-.the^Airport, including botlv-hub carriers United Airlines (United) and American Airlines (American). In November 2016, United announced a renewed focus on domestic network growth, impacting all of its hubs, including O'Hare. In March 2017, United announced 47 new flights and six new domestic destinations from the Airport as a part of its domestic expansion. These changes are expected to result in an overall capacity increase in terms of scheduled seats':of 2.7 percent for United in 2017 compared to 2016. During the same month, American annouriced'its own-expansion at the Airport, adding 10 new destinations to its-route network from O'Hare in addition tb!previously announced new service'to Barcelona, Spain (BCN). These 'new destinations-will account for approximately 45 new daily flights and are expected to result in^an overall-capacity increase in terms of scheduled seats of 2.9 percent for American in 2017 compared to 2016. The new United and American flights began in May 2017 and are anticipated to be fully operational by August 2017-Other notable new service additions in 2017 include Delta adding nonstop service to Seattle (SEA), and WOW Air-adding nonstop service to Reykjavik, Iceland (KEF).

Actual load factors were 87.0 percent through the first 10 months of 2016 compared to 84.5 percent projected in the 2016 Report. Seats per departure are expected to increase as airlines upguage routes to aircraft with greater seat capacity, which in turn allows airlines to operate a similar or greater number of seats through fewer aircraft operations. Overall passenger aircraft operations are not expected to vary significantly from operations as projected in the 2016 Report, based on an analysis of published schedule data available at the time of this Letter. However, as published in current schedules, 2017 scheduled seats per departure are now expected to be approximately one seat per departure higher than projected in the 2016 Report for 2017.
The FAA's 2016 Terminal Area Forecast was released in January 2017. The enplaned passenger growth exceeds that forecast activity in the 2016 Report. Between 2016 and 2025, the 2016 Report forecasts enplanements to increase from 38.4 million to 41.4 million while the FAA 2016 TAF forecasts enplanements at the Airport to increase from .3.7.4 million to 44.3 million in the corresponding Federal Fiscal Years.

Updated Financial Analysis

Changes to the financial analysis since the 2016 Report reflect updated Airport rates arid charges budget information, updated Airport PFC,program highlights, actual debt service on the 2016 Bonds, the issuance of the 2017 New Money Bonds, and updated future GARB debt service assumptions based on the 2017-2021 CIP. The activity projections at the Airport remain unchanged.
As was the case in the 2016 Report, a continuation of the rate-setting methodology set forth in the existing Airport Use Agreement was assumed for the entirety of the Projection Period in the updated financial analysis. While the rate-setting methodology at the Airport following the expiration of the existing use agreement is subject to change, the City remains obligated, pursuant to the Senior Lien Indenture, to set airline rates and charges at a level sufficient to pay the net cost of operating, maintaining, and developing the Airport, including the satisfaction of debt service coverage, fund deposit, and payment requirements of the Senior Lien Indenture. Additional information regarding the Airport Use Agreement can be found in section 5.1.1 of the 2016 Report.
CDA sets a budget for airline rates and charges annually using the rate-setting methodology set forth in the Airport Use Agreement, as described in section 5.1 of the 2016 Report, based on the budgeted Operating and Maintenance (O&M) Expenses, Non-Airline Revenues, required fund deposits, and debt service on Airport Obligations. In the financial analysis presented in Chapter 5 of the 2016 Report, the final

UPDATED. NON-AIRLINE REVENUE PROJECTIONS

The approved, second half 2016 airline rates and charges budget for the Airport served as the base from which Non-Airline,Revenues were projected in the 2016 Report: As shown-in Table A-2 of Appendix A to the 2016, Report, between 2011 and 2015, actual concession revenues generated at the Airport have been higher than the budgeted amount in 3 of the 5 years presented, averaging 2.2 percent higher than budgeted. Actual concession revenues have been within 1 percent of budget in each of the past 3 years. Preliminary data suggests that actual concession revenues, including-parking revenues, in 2016 were slightly above budget.
the Airport has since released its^approved first half 2017 airline rates and.:charges.budget,:.which is now
the base for the updated Non-Airline Revenue projections. The underlying assumptions used to update
the Non-Airline Revenue projections are consistent with those .presented in section 5.3.2: of the 2016
Report. On-going plans involving the renegotiation and remarketing of the expiring concession
agreements-are expected to yield an increase in overall concession revenue through the issuance of new
contracts. .:.(The City is also maximizing the useof,.terminal space to. increase concession ...revenue.,, A

The Terminal 5 Expansion is expected to result in an approximately 20 percent increase in concessions space in-the International Terminal. As a result of this increase, along with expected improved concessions, it is now assumed that the completion.of.the Terminal.5 Expansion will result in a.10 percent increase in concession revenues in the International Terminal beginning 'in 2020. No incremental revenue impacts associated with the Terminal 5 Expansion were assumed in the 2016 Report, but are now reflected in the updated financial analysis.

2017 Refunding Bond Debt Service
It is expected that debt service savings will result from the issuance of the 2017 Refunding Bonds and the refunding of certain Airport Obligations. However, because the actual amount of debt service savings is not yet known, the expected savings from the 2017 Refunding Bonds have not been assumed in the updated financial analysis.
2017 New Money Bond Debt Service
For purposes of the updated financial analysis, proceeds from the 2017 New Money Bonds are assumed to fund $266.8 million in project costs for the 2017 Airport Projects. The 2017 New Money Bonds are assumed to have a term of 35 years, and for purposes of this Report, interest on the 2017 New Money Bonds is assumed at the current market interest rate as of June 6, 2017 plus 75 basis points.
Total debt service payable on the 2017 New Money Bonds is projected to be approximately $15.7 million in 2020, then -increase to $19.5 million in 2021 and remain level during the Projection Period.

Net Debt Service on future GARBs
The updated financial analysis includes Net Debt Service on future GARBs to be issued to fund the remaining OMP Airfield Projects described in section 2.2 of the 2016 Report and the 2017-2021 CIP. Future GARB issuance assumptions include the following:
Future Remaining OMP Airfield Projects GARBs. As presented in section 5.5.1 of the 2016 Report, approximately $361.4 million of the remaining OMP Airfield Projects.are estimated to be funded by proceeds from future GARBs. Funding approval for the extension of Runway 9R-27L" has yet to be negotiated with the Airline Parties and Airline Party approval has not yet been requested or received for these GARBs. Based on the City's planned schedule for the remaining OMP Airfield Projects, Net Debt Service, net of capitalized interest, for these GARBs is assumed to be approximately $42.8 million in 2022 and then remain level through the Projection Period. There have been no changes to the assumed future remaining OMP Airfield Project GARBs since the 2016 Report.

CIP. Similar to the 2016 Report, based on the anticipated timing of capital expenditures and anticipated future Mil airline approvals, a GARB issuance in FY 2018 is assumed in the updated financial analysis. Debt service on these GARBs is allocated to cost centers based on the type of capital'projects funded. Net Debt Service on these future GARBs is projected to be'approximately $20.2 million in 2019, then to steadily increase as projects included in the 2017-2021 CIP are completed to approximately $127.5 million in 2023, and then remain level through the Projection Period.

UPDATED COST PER ENPLANED PASSENGER

. (Fiscal Years Ending December 31)
•$3000""

As described in section 5.8.1 of the 2016 Report, a general test of the reasonableness of airport user fees is to compare projected airline costs in a manner that accounts for airline activity. One approach is to measure airport user fees on a per enplanement (CPE) basis. :A comparison' of Projected Airline Cost per Enplaned Passenger between the updated financial analysis and the financial analysis included in the 2016 Report is presented on Exhibit 7.

As shown, the CPE in the updated financial analysis is projected, to increase from,$18.84 in.2017.to $27.47 in 2025. Notable differences in projected CPE between the updated financial analysis and the 2016 Report include the following:
• Incremental increases in O&M Expenses associated with the Terminal 5 Expansion beginning in 2020

Debt service payable on the 2017 New Money Bonds beginning in 2020
Changes in debt service on future GARBs associated with the funding of the 2017-2021 CIP
The projected Airport user fees in the updated financial analysis are deemed to remain reasonable from the 2016 Report based on the following combination of factors:

Large population and strong economic base - The Airport is located in the third-most populous metropolitan region in the U.S. and is also ranked third in the nation in terms of domestic O&D passengers in calendar year 2016 - following the New York and Los Angeles markets. The Airport's Air Trade Area has a large, diverse economic base that supports business and leisure travel. Projected economic variables indicate that the Air Trade Area will remain a destination that attracts both business and tourist visitors, positively affecting the demand for future inbound airline travel. Projected Air Trade Area economic variables further support the continued growth of local outbound passengers.
Attractive geographical location - The Airport's central location and proximity to heavily traveled east-west airways make it a natural location for airline hub activities and is complementary to airline route networks.
Important hub for United and American - The Airport is a major connecting hub for United and American within their United States domestic route networks, and it is an important international gateway for European, Asian and Canadian passenger traffic, providing strong connectivity to flights of international alliance partners. As estimated in section 4.1 of the 2016 Report, the Airport is the second highest contributor to profit for United and the fourth highest contributor to profit for American. The Airport is also an increasingly important airport within the route networks of several U.S. low-cost carriers. Generally, Airport user fees are not a key contributor to airline's profitability in the U.S.
Increases in debt are associated with capital projects that allow for growth - Airport user fees during the Projection Period are calculated to recover debt service and operating costs partially attributable to significant capital projects designed to provide capacity at the Airport which supports the ability for airlines to increase service. Although the funding of these projects is anticipated to result in increased Airport user fees, these projects support projected long-term growth at the Airport.
In summary, Airport user fees in the updated financial analysis, although increasing over the Projection Period, and increasing over the financial analysis presented in the 2016 Report are one of many factors that are considered by airlines when evaluating air service. Airport user fees were approximately 6.3 percent of system-wide total airline operating costs according to the airline industry group Airlines for
ricondo:
4-.ASSOGIA7.es


City of Chicago, Department of Aviation June 9, 2017 Page 34
America1' and are one of many factors airlines consider when allocating capacity resources. Forecasted growth of population and economic base, along with the geographical location ^and'-established role of the airport in airlines' route network, support the reasonableness of projected Airport user fees.

UPDATED DEBT SERVICE COVERAGE
As presented in Table 1-11 of Attachment 1 to this Letter and in table B-ll in Appendix B of the 2016 Report, the Debt Service coverage ratios are projected to meet the minimum requirement of l.lOx in each year of the Projection Period.

Confirmation of 2016 Report Findings

Qn the: basis of the;assumptions and analyses, described in the 2016 Report and this.Letter,.and our experience preparing financial projections for airport operators, R&A is of the opinion that, for each Fiscal Year of the Projection Period:

¦ ¦• The GARB.debt service coverage ratio will meet the minimum requirement of l.lOx, and
• The airline CPE is considered to be reasonable compared with those at other large-hub airports.

RICONDO & ASSOCIATES, INC. cc: 16-01-0953 06
1.9 percent of passenger airline operating expenses in the fourth quarter of 2016 went to landing fees and 4 4 percent went to non-aircraft rents and ownership, according to data collected by Airlines for America

Summary'of Findings
. Cha^tferl: The 2016 Bonds
Chapter 2: The Airport Facilities,'Capital Program, and 2016 Projects
Chapter 3: Demographic and Economic Analysis
Chapter 4: Air Traffic
Chapter 5: Financial Analysis
On the basis of the analysis set forth in this Report, R&A is of the opinion that the Revenues and Other Available Moneys generated each year of the Projection Period are expected to be sufficient to comply



2016 REPORT [E - 4]
/ <
with the Rate Covenants established in the Senior Lien Indenture, and that the resulting projected airline costs should remain reasonable. Although summary information is provided, a 'complete understanding of the justification for our conclusion cannot be attained without reading the^Report inyits entirety.

Founded in 1989, R&A is a full-service aviation consulting firm providing-ajrport physical and financial
^\;planning services to airport owners and operators, airlines, and federal and^state/agencies. R&A has
prepared Reports of the Airport Consultant in support of over $26 billion of airport related revenue bonds
\ \ j /
since 1996. R&A is not registered as a municipal advisor under"Secti0rWL5B of,t'he Securities Exchange Act
/ / "< \ Xx - -o'
of 1934. R&A is not acting as a municipal advisor and^has notbeen-erigaged by the City to provide advice with respect to the structure, timing, terms, or other similar matters concerning the issuance of municipal securities. The assumptions regarding such matters\included in this Report were provided by the City or the City's financial advisors or underwriters^pr, with^the City's approval, were derived from general, publicly available data approved by the Cfty:|/R&A opes no fiduciary duty to the City. The City should discuss the information and analys1sH:ontain^d\in/th^s Report with internal and external advisors and experts that the City deems appropriate befqre taking any action. Any opinions, assumptions, views, or information contained herein are ndjNif^eTiBelPto be, and do not constitute, "advice" within the meaning of Section 15B of the Securities Exchange Act of 1934.
The techniques and methodologies-used by R&A in preparing this Report are consistent with industry practices for similar studies in^connection with airport revenue bond sales. While R&A believes that the approach and assumpt'idn^Kused'"inlth"is Report are reasonable, some assumptions regarding future trends and events detailed iri'this-Report, including, but not limited to, the implementation schedule and the projections offpasse/iger activity and financial performance, may not materialize. Therefore, actual perforrnance wilMiker^eliffer from the projections set forth in this Report and the variations may be materia^Ih "develogjnj)its analysis, R&A used information from various sources, including the City, the underwriters; /the financial advisors, federal and local governmental agencies, and independent private
' j sproviders of economic and aviation industry data, as identified in the notes accompanying the related tables and exhibits in this Report. R&A believes these sources to be reliable, but has not audited the data and does not warrant their accuracy. The analysis presented is based on conditions known as of the date of this letter.

Airline Parties for OMP Phase 2A included a runway and enabling projects for a future runway. This phase is fully funded; the runway project was completed in October 2015 and the remaining projects are anticioated to remain within budqet. A $1.3 billion infrastructure plan that includes another OMP runway was agreed upon in a funding agreement among United Airlines (United) and American Airlines (American), and the City in January 2016 and Majority-In-Interest funding authority for the plan was approved by the Airline Parties in February 2016. The plan, which includes,Runway 9C-27C, an OMP Airfield Project, and additional airfield improvements not part of the remaining OMP Airfield Projects, which include a centralized deicing pad, a cross-field taxiway systenVaQd relocation of Taxiways A and B, are expected to be funded with proceeds from the 2016-New Mbhey'sBohds, and is expected to be completed by December 2020.

(TAP) is still in preliminary conceptual planning and discussion phases, and while funding for the TAP is expected to include future bond proceeds with debt service payable during the Projection Period, due to the uncertainty of timing and project costs the financial analysis in Chapter 5 of this Report does not include debt service associated with the funding of the TAP. The total investment for the three hotel development projects is estimated to be approximately $350 million and is planned to be funded by a special facility loan(s) backed by hotel revenues. Because a detailed^funding plan does not yet exist for the hotel development, the financial analysis in this Report does'not include future

— 77—p The demand for air transportation is, to aMiegree, dependent upon the demographic and economic characteristics of an airport's\^r^rad^\area. This relationship is particularly true for origin and destination (O&D) passenger traff^tv^hich^a^s^^torically accounted for approximately 50 percent of demand at the Airport (with connecting^p^ssengers-'accounting for the remaining 50 percent). Demand for airline travel at the Airport, therefore, is influenced by the local characteristics of the area served, along with individual airline decisions reg^rdirTg^rvice in support of connecting activity.
The Airjp6rt/s\. Air^rade^y\rea has a large, diverse economic base that supports business and leisure travel. Projected ecotnomic~Variables indicate that the Air Trade Area will remain a destination that attracts both business andlto^ist visitors, positively affecting the demand for future inbound airline travel.

Financial Analysis

R&A completed an analysis that demonstrates the ability of the City to comply with the requirements of the Airport Use Agreement and Senior Lien Indenture in each year of the Projection Period.
The current Airport Use Agreement expires in May 2018. For purposes of the financial ^analysis in this Report,
the existing residual rate-making methodology defined in the Airport Use Agreement's'assumed to continue
1 throughout the Projection Period." However; the ra'te-settirig- methodology coaiajbe' !differeQK|f6lldwing the
expiration of the current Airport Use Agreement in 2018. Even with a differerit'smethodolbgy, the City's
obligations'to bond holders set forth in the Senior Lien Indenture, includinglithe obligation to set rates and
charges sufficient to meet the Rate Covenants, remain. Based on the finahciaNalialysis^in^Chapter'S of this
Report, R&A is of the opinion that the Net Revenues Available for^erM^r^en^Coverage generated by the
Airport in each year of the Projection Period are expected to be sufficient to cor^ply^wtth the Additional Bonds
Tests and the Rate Covenants established in the Senior Lien IndeVi'tu'rvei, ' "
The GARB debt service included in the financial^analysis reflectscdebt service on outstanding GARBs, the 2016 New Money Bonds, and future,GARBs necessary fcir^unding^tbe OMP Airfield Projects and 2016-2020 CIP capital projects described in Chapter 2.

• ^p7)roxim^ately^^73.3 million for the 2016-2020 CIP projects funded with future GARB proceeds.
Results of thejfinancial analysis are as follows:
• Operation and maintenance (O&M) Expenses are projected to increase to approximately $857.1 million, excluding Land Support Area expense, in FY 2025, representing a CAGR of 5.4 percent between FY 2016 and FY 2025. This increase is based on the type of expenses anticipated, the fulfillment of certain assumed City pension contributions described in Section 5.2.2, expectations of future inflation rates (assumed to be 3.0 percent annually) and projected increases to O&M Expenses associated with the completion of OMP Airfield Projects.
« Non-Signatory, and Non-Airline Revenues are projected to increase from $386.3 million in 2016 to $496.0 million in 2025, a CAGR of 2.8 percent. Non-Airline Revenues, include revenues from the Chicago International Carriers Association Terminal Equipment Corporation (CICA TEC); and from

Net Debt Service (including debt service on the 2016 Bonds and projected debt service on future bonds necessary to complete the OMP Airfield Projects and 2016-2020 CIP), net of capitalized interest, PFC Revenues, and Grant Receipts used to pay debt service, is projected to be approximately $423.4 million in FY 2016, then projected to increase throughout the Projection Period to a peak of approximately $537.0 million in 2022, and then projected to decrease slightlvjto $534.6 million in 2025.
The airline cost per enplanement (CPE) at the Airport is estimated to be/appr^ximately^i^^g in 2016 and is projected to increase to $25.46 in 2025 (which equates to/appropriately $19.51 in 2016 dollars). ^^N-//"""""
The projected Airport user fees are evaluated in this analysis to be reasona&e^basecj^on the expectation that these fees will not deter forecasted demand for air traffic at the Airport as airlines continue to deploy capacity to airports based on available resources.

The City has pledged as Other Available Moneys certain Grant Receipts from PAAletter ofintent grants and other FAA discretionary grants to the debt service on the Series 2011B^vnds^n^GrbiTJon to Airport Revenues.

2.1 Airport Facilities
The Airport occupies over 7,200 acres of land 18 miles northwest of downtown Chicago. Its primary facilities consist of the airfield, terminal area, rental car2.1.1 AIRFIELD
Currently, the airfield contains eight actiVe\runways. The existing Airport layout is shown on Exhibit 2-1. The
O'Hare Modernization ProgranrflQMP) includes^reconfiguration of the airfield from intersecting runways to a
predominantly east-west paralleUariway layout. To date, three of the four runways included in the OMP have
been completed and one ofS^he^two planned runway extensions:has been.completed., A discussion of the
OMP is provided in Section 2^j>--A^hetwork of taxiways, aprons/and aircraft holding areas supports the

and the BoeinW47-B^pened in 2013. '' '

2.1.2 ((TERMINAL-AREA
The airlines serving the Airport operate from four terminal buildings with a total, of 189 gates.1 Three terminal buildings, wi^a.total of 170 gates, serve domestic flights and certain international departures. The domestic terminal complex is centrally located within the airfield area. The domestic terminal complex includes Terminal 1 (Concourses B and C), Terminal 2 (Concourses'E and F), and Terminal 3 (Concourses G, H/'J, K, and L). Gates in the domestic terminal complex are leased by the airlines on an exclusive-use basis, with the exception of eight gates in Terminal 3 that are leased on a preferential-use basis and one gate in Terminal 2 and nine gates in Terminal 3 that are accessed on a common-use basis.

A gate is an active aircraft parking position that is accessed through the terminal building, either via a passenger loading bridge or other means, customarily used for enplaning and deplaning passengers. The number of gates is subject to change based on the configuration of aircraft parking.

Terminal 5 (Concourse M), also known as the International Terminal, is located in the eastern portion of the terminal area and has 19 gates and 4 hardstand' aircraft parking positions. The International Terminal serves most international departures and all international arrivals requiring Federal Inspection Services (FIS). In July 2016, the reconfiguration of a gate in the International Terminal to accommodate Airbus A380 aircraft was completed. Gates in the International Terminal are all common-use. The Airport Transit System (ATS) provides transportation among the four terminals and the long-term parking lots.

Also located within the terminal area are a hotel, a parking garage, and the Airport heating and refrigeration
plant. The 10-story hotel, leased and operated by Hilton Hotels Corporation and located directly across from
Terminals 1, 2, and 3, provides approximately 860 guest rooms, as well as restaurants and meeting facilities.
The 6-story parking garage adjacent to the domestic terminals contains approximately:9,300 spaces for public
and employee parking. The heating and refrigeration plant, located northeast of the.domestic terminals,
provides heating and air conditioning for all terminal buildings. A discussion ;pf'.recently announced capital
projects that will impact the terminal facilities, including terminal expansion and . hotel redevelopment, is
provided in Section 2.2.3 of this Chapter. ; ;' v:;>
RENTAL CAR FACILITIES /y o,V-.- / '
On-Airport rental car facilities are currently located on Airport property remote from the terminals; company-specific shuttle buses operate between the rental car facilities and the terminals. Eight rental car brands

The Airport's capital, program includes the OMP Airfield Projects, the 5-year (2016-2020) CIP, and other .recently announced capital projects, which are briefly described, in this section and further described in. Sections 2.2.1 through 2.2.3.
OMP Airfield Projects are changing the airfield from a layout with sets of intersecting runways to a modern parallel runway system. The OMP, which includes construction.of one new runway,-relocation of three existing runways, and the extension of two existing runways;'is being undertakeni;in phases that began in 2005. To date, three of the four runways have been completed and one of the two

Additional information on the OMP, the remaining OMP Airfield Projects, and the additional airfield improvements included in the infrastructure plan expected to be funded with the 2016 New Money Bonds is provided in Section 2.2.1.
2016-2020 CIP includes ongoing repair and maintenance and other capital projects, such as the construction of a Multimodal Facility, which includes a consolidated rental car^facility and public parking facility and an extension to the ATS; airfield improvements associated witlvthe construction of a cargo facility in the northeast area of the Airport; the expansion of tH^Afrport Maintenance Complex; additions and modifications to terminal facilities, including an expansion oftfie International Terminal FIS facility; safety and security projects, including an inline ba|g%a^e\ystemlrVConcourse L and checked baggage inspection station optimization in Terminal l^"d npjse^^cjation.

2.2.1
Under^JJe^MI^ is being reconfigured into a modern parallel runway system, allowing for more
efficient operationsr—Brior. to OMP, the airfield included sets of intersecting runways built upon the original runway configuration of the 1940s. The OMP is a reconfiguration of the airfield into an east-west parallel runway layo^i^.which results in reduced delays and enhanced capacity. The nearly completed OMP. is a comprehensive program providing for the phased reconfiguration of the airfield from sets of converging parallel runways in three main directional. - orientations, (northeast/southwest, east/west, and northwest/southeast) to six parallel runways in the east/west direction and two crosswind runways in the northeast/southwest direction."


The O'Hare Modernization Act, passed by the State of Illinois in 2003, restricted the number of active runways at O'Hare to eight. The OMP includes a plan to decommission three existing intersecting runways, two of which have already been closed, as the east-west parallel runways are constructed, resulting in no more than eight active runways in any phase. A state law signed in 2015 allows up to 10 active runways at the Airport.

The first phase of the OMP Airfield projects (OMP Phase 1) was completed in 2013 with the commissioning of Runway 10C-28C This phase also included the construction of Runway 9L-27R, the extension of Runway 10L-28R, and a new airport traffic control tower, which were all commissioned in 2008. The second phase, OMP Phase 2A, includes the construction of Runway 10R-28L, north airfield enabling projects, and the first phase of the construction of Taxiway LL. Runway 10R-28L was compieted and commissioned in October 2015. The remaining OMP Phase 2A projects areianticipated to be completed by early 2017.

The Airport, in accordance with criteria established by the O'Hare Noise Compatibility Commission, is providing sound insulation of eligible schools and homes as a part of each phase of the^OMR^

2.2.1.2 OMP Airfield Project Benefits
The OMP was developed to address severe aircraft delays at the Airport; The OMP Airfield Projects are reducing delays and enhance airfield capacity. The projects provide the ability to operate triple independent, simultaneous approaches in poor weather conditions and quadruple independent, simultaneous approaches


Sound insulation may include the following: installation of heating and air conditioning systems, replacement of existing windows and exterior doors with sound-insulating windows and doors, addition of dry wall to interior walls, and addition of baffling devices to exterior vents.

in clear weather conditions. Additionally, the OMP includes construction of two ADG Vl-capable runways, Runways 10C-28C (completed in 2013) and 9C-27C (anticipated completion in 2020), which meet standards for aircraft with wingspans exceeding 214 feet. ADG VI aircraft include the Airbus A380 and Boeing 747-8.
Since the implementation of the OMP Airfield Projects, the arrival and departure throughput rates at the Airport have increased. With the opening of Runway 9R-27L and the Runway 10L-28R extension in 2008, Runway 10C-28C in 2013, and Runway 10R-28L in 2015, the average hourly arrival throughput rates have increased approximately 20 percent. The runway projects eliminated "converging runway^pperations," which were addressed by the FAA in 2014 nationwide with the implementation of new rulesj^manage runways with converging flight paths, which further decreased the efficiency of O'Hare's intersecting runways. Without the OMP Airfield Projects, the Airport's capacity could have been further reduced^asTaResult of th^'converging runway operations" rule.

Annual aircraft operations at O'Hare reached a high in 2004 of nearly^millj.on\c^aJ^annual operations. Since the peak in 2004, annual operations have remained relatively stea'dy.^a^eraging approximately 880,000 total operations per year since 2010. While annual operations have remained steady/ peak hourly demand at O'Hare was at a 10-year high in 2014 and at a similar level in^2015.\This peak/riourly demand is partially due to the rebanking of flight schedules by both major airJji^^at^OjHare^Sllbwing them to concentrate and reduce connection times during peak travel periods. Thes-i^crease-'in throughput gained from implementation of the OMP has provided the airfield capacity necessary to handle this flight schedule rebanking.

Airport due to;the High Density Rule6 ano>FAA flight caps



The High Density Rule is a federal regulation established in 1969 to manage congestion at five high density airports, including O'Hare. The rule established limits on the number of all take-offs and landings during certain hours. The rule was relaxed by the U S. Congress in 2000 and was phased out completely at O'Hare by July 2002. ,
In November 2004, the FAA and the airlines serving the Airport agreed to voluntarily limit scheduled domestic and Canadian arrivals at the Airport. In October 2006, the FAA implemented a formal flight reduction rule at the Airport (with the same limitations that were voluntary), which expired in October 2008.

2.2.3 OTHER RECENTLY ANNOUNCED CAPITAL PROJECTS

The City is undertaking capital projects intended to provide Ajrporf\facilities with' the ability to accommodate
long-term demand into the 21st Century-'-'Recently anno this demand are
described in the following sections.

2.2.3.1 Concourse L Extension
In February 2016, the City announced ah'expar^si^r^prpject-of> existing Concourse L in Terminal 3. Five new

2.2.3.2 Hotel Development
In June 2016, the Cit)^nnouncecI^th"ree¦ hotel development projects to-add capacity at .the Airport. The projects includelhe cc^nstructicin of two newrhotels and the modernizationiofrthe existing, terminal hotel. CDA intends to. deyelop^ahnew hotel1: adjacent to the International "Terminal, accessible.ito theiATS, with 300^100 rooms, 25,000^65,000square feet of conference space, banquet rooms, and other amenities. A second 150-200 roo^^otel^^pected to be developed by a third party as part of a new mixed-use commercial development]adjace~nr1io the Multimodal Facility and adjacent to a 200,000 square foot office, complex. Both
^ if
will .also be accessible to the terminals via the ATS., Plans also exist for a renovation and modernization of the existing, terminal hotel when ,the current, lease, expires in 2018. The total investment for the three development projects is estimated to be approximately $350 million, planned to be funded by a special facility loan backed by hotel revenues, and construction is expected to be complete between 2020 and 2022.

The total estimated cost of the Multimodal Facility included in the 2016-2020 CIP is $782 million; which is fully funded through a combination of previously issued GARBs and the Airport Development.Fund ($158 million), PFC Revenue (pay-as-you-go) ($3 million), CFC pay-as-you-go revenue ($166 million), previously issued CFC revenue-backed bonds ($183 million), and a U.S. DOT TIFIA direct loan ($272 million) secured by CFC revenues on a subordinate basis to the CFC bonds. The total estimated project cost'is currently $785.4 million, which reflects ah additional $3.4 million of project costs agreed'to pursuant to a letter agreement between the City and the rehtal'car companies.

Report of the Airport Consultant g2 2016 REPORT [E - 44]
CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT


Requests for Proposals for an Operator Agreement for the terminal hotels and for a Development Agreement for the mixed-use commercial development are expected to be issued in the fall of 2016. Because a detailed funding plan does not yet exist for the hotel development, the financial analysis in this Report does not include future funding of this project.
Terminal 5 Expansion
The City is undertaking an expansion and set of modifications to Terminal 5 to accommodate increased traffic at the Airport. The current gate configuration in the terminal does not provide optimal sclieduling of aircraft, as smaller gate sizes are not compatible with capacity demand. The Terminal 5 Expansionjncreases both the number (from 19 to 28) and the size of gates in Terminal 5. The project includesan extension of the east concourse of Terminal 5, which includes the addition of approximately 279,000^uare Teet of gross floor area; the addition of 9 aircraft parking positions and installation of associated passe^g^rflpading^bridges; and the extension of sterile corridors feeding the FIS facility. The project also inj^udes^the' expansion of the existing terminal apron by approximately 1.5 million square feet, increasing^tot^lJinear^feet of gate frontage by approximately 25 percent.
The Terminal 5 Expansion also includes the reconfiguraticir^of^ concourse of Terminal 5.
Gates Ml through M6 will be modified to accommodate eigjrt/narrowbody aircraft. Existing passenger
loading bridges will be modified, and new passenger^loading^b'ridges will be added to provide access to the
terminal for the reconfigured gates. Existing T^eyninaj^S fa^cniities will also be modified to accommodate
additional activity anticipated from the terminal^^pansjoTi^and the modification of existing gates.
Modifications to systems include the exp^nsion^of^e^ecunjty screening checkpoint; the modification of the
baggage system, ticket counter lobby^a^ilities^^nd FlSqfi^pection areas; and other projects. Also included in
the project is the Airport's second AirbusxA38^brcap_3ble gate, with holdroom space specifically designed for
the aircraft. x <
It is anticipated that the Terrninal-5-.Expansion will be completed in 2019 at a cost of $266.8 million. The project will be funded with PFC^evehLte (pay-as-you-go and PFC Revenue Bonds anticipated to be issued in 2017 to fund approximately $188.6_million of project costs) and Airport discretionary funds, and no airline approval is required. Additional inte'ffnation regarding future PFC Revenue Bonds is provided in Section 5.4.1 of this Report.-
Terminal AreaNRIan
In addition Vto near-term gate expansion projects, long-term terminal development, and redevelopment options are jbemcpevaluated as part of a recently announced Terminal Area Plan (TAP). The City's goals include strengthening the Airport's connectivity, capacity, and efficiency; improving passenger experience; and modemizing^existing terminals and their functional and commercial spaces. The City and airline representatives are collectively evaluating terminal development options. Current plans under consideration for the TAP include the redevelopment of Terminal 2 into a new central terminal within the existing terminal complex. Amenities in the new terminal could include a new U.S. Customs and Border Protection facility, a departure hall with additional space for TSA passenger screening, concessions, and passenger amenities. The TAP also examines new concourses to be constructed to the west. The TAP is still in preliminary conceptual planning and discussion phases, and while funding for the TAP is anticipated to include future bond proceeds with debt service payable during the Projection Period, due to the uncertainty of timing and project costs, the financial analysis included in Chapter 5 does not include any debt service payments associated with the TAP.

Report of the Airport Consultant
Ci I V OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT


The TAP would allow the Airport and airlines serving the Airport to address the constraints of the existing terminal infrastructure in order to enable long-term growth. The International Terminal, which was completed in 1993, was the last major addition to O'Hare's terminal gate capacity. Since then, significant investments in increasing airfield capacity have been made to address airfield delays and to provide long-term capacity. Concurrently, the airline industry has pursued severai changes that have buiit additional pressure on the Airport's existing terminal infrastructure. Increasing aircraft gauge has impacted the capacity of existing gates. The industry has also experienced changes in functional areas, such as security screening, impacting the usability, of the existing terminals. Therefore, the JAP could,provide increased capacitj^pf'aircraft gates and terminal processing areas, while also meeting functional needs in several areas. ¦

2.3 The 2016 Projects

A portion of the proceeds of the 2016 New Money Bonds is anticipated'tO;b.e>used;to fund the 2016 Projects,
which consist of the construction of Runway 9C-27C and enabling projects inciuding^airline facility relocation;

3. Demographic and Economic^nalysis


The demand for air transportation is, to a large degree, dependent upon the,,-demographic\and economic characteristics of the geographical area served by an airport, commonly referred an airport's air trade area. This dependence is particularly significant for O&D passenger traffic^w^icj^nathistorically accounted for approximately half of the passenger traffic at the Airport. ^he^jr^jc^r\^ortion of demand for air transportation at the Airport, therefore, is influenced more by the^lpcal characteristfe of the area served by the Airport than by individual airline decisions regarding service patterns in support of connecting activity.

Population growth is'a key factor creating demand for airline travel. Data in Table 3-1 show that the Air
l ' a.
Trade Area added^approximately 329,000 to its population between 2005 and 2015, or approximately 32,900 per year. Thi2/Air Trade Area's historical rate of population growth was higher than that of the Midwest population, but it was lower than that of the United States—a relationship that is expected to prevail through 2025. The Air Trade Area population forecast for the period 2015 through 2025 reflects a compound annual growth rate (CAGR) of 0.6 percent—a rate that is higher than what is projected for the Midwest (0.4 percent) but lower than what is projected for the United States (0.9 percent). The projected increase of approximately 560,000 new residents in the Air Trade Area during this period is expected to generate additional demand for airline service at the Airport.

of 204,000 jobs per month." Between January and August 2016, U.S. employment growth averaged 182,000 jobs per month.Continued monthly job growth supports projections for wage gains and further declines in unemployment. In addition, the outlook for consumer spending is optimistic, inflationary pressures are modest, and lower oil prices are projected to have a positive effect on U.S. growth.'7

The most recently published projection by business economists from the National Association for Business
Economics (NABE) indicates consensus for real GDP growth of 1.5 percent in 2016 and 23 percent in 2017.
The NABE estimates that the average annual U.S. unemployment rate will be 4.8 percent in 2016 and 4.6

period is the incre?
regional/commuter affiliate operations relative to those of majors/nationals. As airline labor agreements have become less restrictive, airlines have increased the amount of capacity flown using regional aircraft, specifically those seating more than 60 passengers. This has allowed airlines to increase average seat capacity through the use of larger regional jets. The trend toward regional/commuter affil^t^pperations at the Airport began to change in 2015, however, as airlines increasingly replaced smallenregional jets with larger regional jets and mainline aircraft. Over the period shown (2006-2015), relaxation of restrictive labor agreements has enabled a 1.0 percent compound annual decrease in-total operations at the Airport, which, as shown on Exhibit 4-11, is similar to operations trends at the 10 largest North-Amerjcan-a'irports.

After an approximately. 49 percent decline in 2007 (from 31,912 operations in 2006), general aviation operations-have grown from 16,295 in 2007 to 21,828 in 2015. General aviation activity levels at the Airport are influenced by the lower costs and lower delays at outlying airports within the Chicago region. As a result, general aviation activity at the'Airport has been relatively low, accounting for approximately 2.5 percent of total operations in 2015.

The second busiest all-cargo carrier at the Airport is United Parcel Service (UPS) with approximately 3 daily departures Approximately 54.9 percent of all-cargo operations in 2015 were international flights. Operations by the all-cargo airlines at the Airport were relatively stable in 2006 and 2007, averaging approximately 21,000 operations during this period. All-cargo operations at the Airport decreased 15.2 percent in 2008 from 2007 levels, primarily' due .(to "the temporary discontinuation of service at the Airport by Korean Air Cargo and the decrease :ih£ervTce^at^the Airport by FedEx and UPS due to increases in fuel price's during this period.

STATE OF THE AIRLINE INDUSTRY
In the aftermath of the terrorist attacks on September 11, 2001, the United States airline industry experienced a material adverse shift in the demand for airline travel, which exacerbated problems for a United States airline industry already weakened by a slowing economy and rising labor and fuel costs. The result was 4 years of reported industry operating losses in 2001 through 2004, totaling more than $22 billion (excluding extraordinary charges and gains). Following these restructuring years, the airline industry gained ground from

2005 through 2007, with United States airlines posting combined operating profits in all 3 years.5 In 2008 and through the first half of 2009, the combination of record-high fuel prices, weakening economic conditions, and a weak dollar resulted in the worst financial environment for United States network and low-cost airlines since the September 11, 2001 terrorist attacks.

4.4.3 AIRLINE MERGERS AND ACQUISITIONS ^
Since 2009, airlines have merged or acquired competitors in an attempt to increase operational synergies and become more competitive and cost efficient. In 2009, Delta completed its merger^yvitri^Northwest Airlines, initiating a wave of United States airline mergers and acquisitions. That same year,-Republic Airways Holdings, a regional airline, acquired Frontier Airlines of Denver and Midwest Airlines of^Milwaukee. In October 2010, United and Continental merged, creating the world's largest airline in terms o^qp^atmg^revenue and revenue passenger miles. In 2011, Southwest Airlines acquired AirTran Holdings,-lQC, tfie^ormer parent company of low-cost competitor AirTran. Effective December 9, 2013, Americao-'a^^USsAirvvays merged, creating the largest airline in terms of operating revenue and revenue passenger miles (surpassing United). Additional consolidation in the United States industry could affect the' amountXof capacity offered to passengers and alter the competitive landscape.

4.4.3.1 Capacity Discipline —A Change in the Airline Business Model
In 2008, many domestic airlines announced significantpcapaeitv^ reductions, increases in fuel surcharges, airfares and fees, and other measures to addr^ss>^heir ^nancial challenges. In 2008 North American International Air Transport Association ^ir(in^Yecbr^e^d^^$16.8 billion loss. The combination of airline mergers and capacity reductions has/dramatioaHy improved the financial conditions for the airlines. In contrast to earlier losses, North American^nteTnatJonal Air Transport Association airlines are projected to generate profits of $22.9 billion in 2016, af|er producing $21.5 billion in profits in 2015.10 Strict control on capacity, primarily in the domestic market, referred to as capacity discipline, is the principal driver behind the airline industry's financial tum'aroulid^Capacity discipline reflects; a shiQSn^the airline business model, from an environment where market share targets are pursued tc/ one^where financial targets are pursued.

passenger volumes have not followed GDP trends since 2009, another measure of passenger demand, passenger revenue, has increased as United States airlines have focused on achieving financial targets through lower domestic passenger volumes and higher passenger fares. United States domestic seat capacity increased in 2015 and is scheduled to increase further in 2016 as airlines have taken advantage of lower fuel costs to increase capacity to achieve financial targets through growth of passenger volumes.

COST OF AVIATION FUEL
The price of fuel is one of the most significant and volatile expenses for airlines. Historically, fuel has been the first or second largest operating expense for the airline industry, shifting with labor as the cost of fuel fluctuated. According to the International Air Transport Association (IATA), fuel was 31.6 percent and 27.5 percent of operating costs for airlines in 2014 and 2015, respectively, and is projected to be 19.7 percent of operating costs for 2016.11 /}
Exhibit 4-14 shows the monthly average prices of jet fuel and crude oil from Janda'rys-2007 through June

Midway is a hub for Southwest Airlines and serves as the largestfairport in its-system when measured by both enplaned passengers and operations. In 2015, 43 of Midway's top 5C3pdomestic O&D markets were included in O'Hare's top 50 domestic O&D markets. Internationaliservice from Midway includes flights to Canada, Mexico, and the Caribbean. Long-haul internationalrnarkets cannot be served from-Midway due to constrained runway lengths.
Table 4-12-presents enplaned passengers for the Airport and Midway between 2006 and 2015. The Airport maintained nearly 81 percent share of total enplaned passengers between 2006 and 2008 despite Southwest's expansion of service at Midway during the period after the bankruptcy of ATA Airlines. Between 2010 and f2013, however, as Southwest grew at Midway, enplanements at the Airport remained relatively stable. As a result, Midway achieved an enplanement share of greater than 23 percent by 2013. However, as the Airport outpaced Midway in enplaned passenger growth in both 2014 and 2015, the Airport's share of total-enplaned passengers increased from the low experienced in 2013.

Table 4-13 provides a comparison of average fares and yields for the Airport and Midway. The average fare and yield growth for the Airport and for Midway were similar in 2006 and 2007. In 2008 fares and yields grew more at Midway as a result of the bankruptcy of ATA Airlines. After decreasing in 2009 as a result of the economic recession, fares and yields began to recover at both airports in 2010. Fares and yields grew at Midway in 2011 and 2012 as Southwest added additional service on longer range routes from Midway. After a slight drop in average domestic fares at the Airport in 2012, domestic fares and yields at both airports grew by a modest rate in 2013 and 2014.

4.5 Importance of the Airport to Airlines


4.5.1 HUB AIRLINES /\';
The Airport represents a strategically important element of the route networks of Unfted and American, and is estimated to be the second and fourth highest contributor to their profit, respectively. Measured by seat capacity, it is currently the largest hub in United's network and the fourth largest hubln American's network, and has the second largest number of O&D passengers for both hub airlines. \X <-y " •

Exhibit 4-15 presents the estimated operating profit and relative contribution: of each of the airlines' hubs.
Publicly available sources of financial and operational data were;;analyzed, and allocation methodologies
commonly used in the airline industry were applied to derjve esti^ financial performance. Ticket
revenue was attributed to hubs using DOT O&D data and prorated'to flight segments using a distance-based proration methodology. Non-ticket revenue was alJocated>usihg drivers that include passenger and cargo
f* ::'r' !'
volumes. Cost allocation drivers include block hours; departures, passenger volume and Available Seat Miles (ASMs). Aircraft type-specific allocation rates were used^u/here reporting is available in order to represent the economic impact of the mix of fleet typesoperating across the hubs. While this analysis has applied commonly used approaches to the alignment'rof costs -and revenues with activity based allocation drivers, these estimates of hub profitability may diffecifrom those developed by individual airlines, which employ many different methodologies incorporat'ing;aetailed internal data sources. Based on this analysis, the Airport is the second highest contributor to profiteer United and the fourth highest contributor to profit for American. ^

As shown on Exhibit 4-16, the^Airport .contributes the third most revenue among United's hubs and the fifth most revenue among,. American's hubs. Table 4-14 and Table 4-15 present the percentage of O&D passengers flo\^-by,JJnitedva(jd American at their hub airports in 2015. The Airport serves 17.5 percent of United's hub >0&D passenger base and 14.1 percent of American's hub O&D passenger base, and represents the second-largest O&D-passehger base for both United and American^ :
The central geographic location of the Airport allows United and American to efficiently connect passengers within the United States and to many international destinations. As other airports have been dehubbed either through consolidation or as a result of the industry's implementation of the capacity discipline business model, United and American have leveraged their hubs at ORD to accommodate more connecting passengers, especially as underlying market demand grows.

As shown in Table 4-18, since 2009, departures operated collectively by Frontier, JetBlue, Spirit, and Virgin
America have increased at the Airport by nearly six-fold (from approximately 10 daily departures in 2009 to
approximately 56 daily departures for the 12-month schedule period ended August 2016). During this same
period, average daily low-cost carrier seat capacity at the Airport has increased from 1,335 daily departing
seats in 2009 to 9,369 daily departing seats in 2016. This low-cost carrier growth has occurred at the same
time as record growth by Southwest at Midway, indicating growing demand for low-cost carrier service at the
Airport concurrent with growth at Midway. * ¦ , "",

Foreca^fl^liKa^^ (i.e., enplaned passengers, aircraft operations, and landed weight) were
developed crnisiderihg''historical activity, including passenger volume and revenue trends at the Airport and across the industry", historical trends and future forecasts of local and national socioeconomic factors, and anticipated fJripds in use of the Airport by American, United, and other airlines. The following section provides an overview of'the methodologies used in forecasting activity at the Airport, and it also presents the results of those forecasts through 2025.
4.6.1 ASSUMPTIONS UNDERLYING THE FORECASTS
Forecasts of enplaned passengers, aircraft operations, and landed weight were based on a number of underlying assumptions, including:
The Airport will continue its role serving O&D passengers and as a major connecting hub for United and American Airlines. The Airport will continue to serve as a connecting hub within the United States

4.6.3 LONGER-TERM (2018 THROUGH 2025) ENPLANED PASSENGERS FORECAST METHODOLOGY
To understand the long-term growth potential of enplaned passengers at the Airport, forecasts of nationwide and local economic activity were examined, as discussed in. Chapter 3 of this Report. It was concluded that the economic bases of the Air Trade Area and the nation are diversified, stable, and capable of generating longer-term increases in demand for air transportation at the Airport during the Projection Period.
in aviation activity using forecasts of independent variables, socioeconc R-squared represents
70 percent or better was considered adequate
Longer-term passenger demand growth rates at the Airport were derived using socioeconomic regression analysis. Socioeconomic regression analysis is used to identify predictive relationships between a dependent variable (e.g., passenger volume, passenger revenue, or other metric representing^passengeiCdemand) and one or more independent variables (e.g., socioeconomic factors, such as population,).employment, per capita personal income, etc.). These relationships, or regression models, can be emplo.yecLto-foretast future growth
A standardVneasure of how well each

socioeconomic variable explains passenger demand is the regression/fooders^oeffieient of determination, or A result of 100 percent is the maximum value possible for a coefficient of determination; it represents a perfect fit between the variables analyzed. For^pJOrppsesNqf thisyanalysis, an R-squared value of
Socioeconomic regression analysis was conducte^to identif^predictive relationships between passenger
demand at the Airport and socioeconomic variables at4r>e national level and for the Air Trade Area16. The
Airport serves originating passengers who resid^r^t^e'^Air Jra"de Area as well as those who visit or connect
through the Air Trade Area or Airport^r-''b"rjsinesssoU With the Airport's diverse customer base,
demand for air service is driven by factors directlyj^ated to demographic and economic characteristics of both the Air Trade Area and the natioir>^A-^sti^n7*i:he following five socioeconomic variables were analyzed separately as independent variables in the\ecjression analyses, both for the nation and the Air Trade Area: population, income, per capita'personal income, employment, and GRP/GDP.

As a result, predictive relationships between the Airport domestic passenger volumes and socioeconomic elements were not adequate for use in forecasting future domestic air traffic.

Also as illustrated in Exhibit 4-12 and Exhibit 4-13, the historical'relationship between international passenger volumes and socioeconomic factors has remained intact, as airlines have continued to accommodate more-profitable international passengers. As a result, adequate regression models were

In order to derive passenger volume growth associated with the range of forecasted passenger revenue growth, a second step was necessary to estimate how airlines might capture that revenue at the Airport, through a combination of passenger volume growth and/or passenger fare growth. A range of revenue to passenger "conversions" was developed for application to overall revenue growth forecasts.




Report of the Airport Consultant
L I j Y Ul" L H IL l\MJ
CHICAGO O HARi: INTERNATIONAL AIRPOR I



The Airport's relatively high yield and low historical passenger component of revenue growth indicates an environment where airlines are more able to support profitable passenger volume growth (in contrast to the recent environment where revenue growth has come almost entirely through fare growth). These conversions were derived through analysis of recent trends of revenue growth in the United States industry, and span a range from conservative (low passenger volume growth - 13 percent of passenger revenue growth is driven through passenger volume growth, modeled using fare growth trends at the Airport over the last decade) to aggressive (high passenger volume growth - 66/p^rcent of passenger revenue growth is driven through passenger volume growth, modeled consider,}ng the^FAA's forecast of
' industry yield growth as published in the FAA Aerospace Forecast 2014-2034). For reference ^purposes, between 2009 and 2014, passenger growth has accounted for approximateiy?20 percent of revenue growth at the Airport, and 27 percent for- the top 30 United States airports. Betivee^2^012 and_ 2014, passenger volumes-accounted for approximately 50 percent of revenue growth .both at the Airport and in the top 30
: United States airports. Between . 2013 and 2014, approximately'''fb^perc^t^fyrevehue growth at the Airport wasldue to passenger volumejgrowih, compared to 60 p^e^cent in the top 30 United States^airports.

C) Both Socioeconomic Variables and Average Fares, and Passenger Volumes (Multi-Variable Regression): Regression analysis was performed to enable forecasting of passenger volumes given forecasts of socioeconomic" variables and a range of possible average fares. Under this regression methodology, several adequate relationships were identified for the domestic and international O&D passenger segments. However, the results of this approach were significantly more aggressive than those generated under the approach described in "B". Therefore, the results of this approach were dismissed.

! CITY 01 CHICAGO I
I CHICAGO O'HARE INTERNATIONAL AIRPORT NOVEMBER 1.8, 2016



D) Socioeconomic Variables and Regional Passenger Volumes (Single-Variable Regression):
To take into account the other airports in or around the Air Trade Area, Midway and General Mitchelt, regression analysis was conducted for O&D passenger volumes at the combined airports and socioeconomic variables in both regions. Forecasts of the Airport's share of O&D passengers among the three airports were applied to those relationships with adequate R-squared values in order to determine the O&D passenger forecast. The approach yielded a more aggressive result than those produced under the approach described in "B". Therefore, the results of this approach were dismissed.'

4.6.3.3 Enplaned Passenger Forecast Results
In the forecast included in the 2015 Report, a scenario was selected from the range of passenger volume growth produced by the Socioeconomic Variables and Passenger Revenue approach to forecast enplaned passengers through 2024. This scenario (which produced a 2014-2024,compound annual growth for total enplaned passengers of 1.6 percent) was selected in part for its lower outlook on revenue growth. In addition, the scenario assumed a conservative-to-average passenger conversion. The outlook for revenue growth, as forecast in the 2015 Report remains unchanged in the forecast, in thiSsReport. /However, the recent reduction in the cost of fuel has resulted in lower-than-expected passenger fares:lri'-2015 and 2016. As previously described, this decrease in fares has helped sustain highecyplum^s of enplaned passengers in 2015 and 2016. Fares were modeled to gradually return to levels forecast previously, under the assumption that fuel prices will increase in the future. The long-term enplane^d'passenger vVumes are still expected, but incorporate the recent growth in the near-term. This analysis assumes-that fuel prices eventually return to a higher level. If
\ *¦.'¦¦¦ y S
fuel prices remain low for a longer period of.tirfie, fareSs.may;^also grow at a rate lower than forecast. This could result in a higher volume of enplaned passengers' than forecast.

Enplaned passenger forecasts are presented\in Table 4-19, re-categorized by domestic and international as indicated in Airport reports, /rjhe'number oHoternational enplaned passengers is forecast to increase from approximately 5.5 million in 2015 to approximately 6.5 million in 2025, at a CAGR of 1.6 percent for the period.

Forecasts of jpjassenger airline aircraft operations are based on assumptions of load factor management by the airlines serving,trte'Airport and analysis of future fleet plans. Passenger airline aircraft operations are forecast to increase at- a CAGR of 0.1 percent during the Projection Period, with the majority of passenger growth being accommodated through use of larger-capacity aircraft. Specific information regarding forecasts of passenger airline aircraft operations is provided below:

• Average seat capacity for passenger airline aircraft operations at the Airport is expected to increase from 105 seats in 2015 to 117 seats in 2025. This capacity increase is driven primarily by a shift by United and American away from aircraft with 50 or fewer seats to both larger regional jet aircraft and narrow body mainline aircraft. Airlines are able to maintain seat capacity in markets while reducing

Chapter 5 presents the following projections: Operating and Maintenance (O&M) Expenses; Non-Signatory Airline and
federal funds; Net Debt Service; the Net Signatory Airline r^equir^meq^.ajTd.,ca Airport rates and charges. The reasonableness of Airport^dser fees, incluciing
Non-Airline Revenues; Other Available Revenues, including PFC \Reyenue and Grant Receipts, and other
and General Airport Revenue Bond (GARB) Debt Service cdv.eVage'are also discussed.

Bonds, and future GARBs necessary for fL^cimg the OMFairfield Projects and 2016-2020 CIP capital projects
described in Chapter 2. It is expecte^^a^a^nnuaLd^t service savings of between $2.1 million and $7.5 million will result from the issuance of\^e^2016~Refunding Bonds and the refunding of certain Airport Obligations. The expected sayings^rom theN2{H6 Refunding Bonds have been assumed.

In combination, the 2016 Ne^fvloney^Bonds and future GARBs assumed in the financial analysis reflect the following capital projer^funding^s^upiptions:

approxirr5afj^$1.3 billiojj for remaining OMP Airfield Projects, including $978.3 million for Runway 9C-27C furided witJr proceeds from the 2016 New Money Bonds and $361.4 million for the extension of RunwvaV'v9R-27L funded with future GARB proceeds,
,approximately-$289.5- million for additional airfield improvements, including $113.3 million for the centrjbize^d^deicing pad and $176.2 million for cross-field taxiway system and relocation of Taxiways A and B^btoth funded with proceeds from the 2016 New Money Bonds, and
• approximately $773.3 million for the 2016-2020 CIP projects funded with future GARB proceeds.
Financing assumptions of the 2016 New Money Bonds and future GARBs are described in Section 5.5 of this Chapter. Future PFC Revenue Bonds, anticipated to be issued in 2017 to fund approximately $188.6 million of the Terminal 5 Expansion project and to potentially refund certain outstanding PFC Revenue Bonds, are described in Section 5.4.1. of this Chapter.

The other recently announced capital projects, including the Concourse L Extension, Hotel Development, and the Terminal Area Plan, as described in Section 2.2.3 of this Report, are not included in the financial analysis.

Report of the Airport Consultant

NOVEMBER 18, 2016



While costs for these projects are likely to be incurred during the Projection Period and future bonds could be issued to fund certain portions of the projects with debt service payable during the Projection Period, the projects are in preliminary planning phases and project timing and costs have not been fully developed and are currently unknown.

Anticipated funding sources for these projects are as follows: />. '
7.y
y,-:• Concourse L Extension. To be funded directly by American Airlines. ^y ^Hotel Development at the Airport. To be funded through a special facilitylqan, or loans, backed by hotel revenues.

The'Terminal Area Plan is still in.the preliminary conceptual planning^nd^disc^ussjonphases. Funding sources
have not yet been determined. , // \\ \
5.1 Financial Framework :

The Airport is owned by the City, operated by CDA^and is accounted for as a self-supporting enterprise fund
. of the-City on a Fiscal Year, basis.: The,.City's>'fl^ 31. The-City maintains the books,
¦ •• records; and accounts of the Airport in accor^nce^ith generally accepted accounting principles and as ». - required; by the provisions .of, the 'AirporUUse -Agreement arid the Senior Lien Indenture; Neither Gity nor State .-of rlllinois'tax r.eVenues-.-are ipledged Ao^'^--.pa^en.^o.f^iet • Debt Service or to fund the .cost of operations at the Airport.

In the. aggregate, the Airline Parties, including-their regional affiliates, accounted for approximately 76.0% percent of the total landed weight at the Airport in 2015. Non-Signatory Airlines, the airlines that are not signatory to the Airport Use Agreement or a regional affiliate to one of the Airline Parties, including foreign flag-carriers, accounted for the remaining 24.0% percent of landed weight at the.Airport in 2015. Foreign Flag carriers that: have signed the International Terminal Use Agreement are referred to as the International Terminal Airline Parties. The Airline Parties and the.International Terminal Airline Parties are collectively referred to as the Signatory Airlines in this Report. '





Report of the.Airport Consultant 168 2016 REPORT [E -120]

CITY OF CHICAGO
CHICAGO O'HARE INTERNATIONAL AIRPORT



Upon the expiration of the Airport Use Agreement in 2018, the City and the Airline Parties could agree to execute a new agreement as the result of negotiations between the City and airlines serving the Airport or the City could elect to impose airline rates and charges without an airport use agreement and in accordance with the FAA's Policy Regarding the Establishment of Airport Rates and Charges.

The City has initiated efforts to evaluate options for a new Airport use agreement that will maximize the use of
existing terminal facilities and provide a mechanism for the City to fund future capital^prdjects. While there
are multiple rate-setting methodologies that may achieve these goals, in any case/tiie City is obligated,
pursuant to the Senior Lien Indenture, to set airline rates and charges at a level^sufficient topay the net cost
of operating, maintaining, and developing the Airport, including the satisfa^tidrTofi-debt service coverage,
fund deposit, and payment requirements of the Senior Lien Indenture. Profections^dr^Q&M^ Expenses, Non-
Airline Revenues, and Net Debt Service assumed in the financial analysisNr^'^ are developed
independently and material changes to these projections resulting/froiTrcr^ngesQr^ the airline rate-setting
methodology at the Airport are not anticipated. ( f

Although the City is contemplating options for a business,deal, the^ ratecsettihg methodology after May 2018
is uncertain and remains subject to negotiations betwe^n^tlje^/City and the airlines serving the Airport.
Therefore, in developing the financial projecticms^presente^d herein, a continuation of the rate-setting
methodology set forth in the existing Airport U^e^Agreerrjent was^assumed for the entirety of the Projection
Period. It is also assumed in this Report that the^tfrrent Airline Parties and International Terminal Airline
Parties will continue to be signatory to j:ufur^ will remain signatory to those agreements
through the Projection Period.

5.1.2 AIRPORT FEES AND CHARGES'
Under the current Airport Use/AgTeement, terminal rental rates and airline landing fees are established using a
residual airport rate-setting ir^etjjodblcigy1, whereby airline rates and charges are calculated to recover any net remaining costs for e^ch Cos^ev^rju'e Center (CRC). To equitably allocate the net cost of operating, maintaining, improvingA^d expandihg'the Airport among the Airline Parties, various physical and functional areas of the Airport^are separated into CRCs for the purposes of accounting for O&M Expenses, revenues, required fund (deposits, and Debt Service on Airport Obligations. An allocable share of the net deficit generatedJn tlikTermiPic|l Area, Airfield Area, and Fueling System CRCs .is paid by the Airline Parties as part of their AiFpoiy ^es^jjwd^Gharges for the use of the Airport. The Airport Use Agreement provides that the 't Airport Fees and Charges paid by the Airline Parties must be sufficient to pay the net cost of
aggregate of
operating, maintaining, and developing the Airport (excluding the Land Support Area), including the satisfaction o,Fdebt service coverage, deposit, and payment requirements of the Senior Lien Indenture. Airlines or other users of the Airport that are not signatories to the Airport Use Agreement or the International Terminal Use Agreement are assessed Airport fees and charges enacted by City ordinances. For financial




A somewhat modified rate-setting methodology is in effect for portions of the Airfield Area in order to avoid "private business use" under federal tax regulations. See Section 5.7.1 herein.

projection purposes, it was assumed that the City ordinances controlling non-signatory airline fees and charges will remain in place through the Projection Period.

Five CRCs in the Airport's financial structure are included in the residual rate-setting calculation and the adjustment of Airport Fees and Charges, as follows:
Airfield Area. The Airfield Area includes the aircraft parking areas, runways, taxiways, approach and
runway protection zones, infield areas, navigational aids, and other facilities rela'te:dvto aircraft taxiing,

compound annual growth rate of 3.4 percent, from $407.3 million in 2011 to $466.4 million in 2015. This increase in O&M Expenses can partially be attributed to increasing professional and engineering costs as well as increases in salaries and wages. Between 2011 and 2015, professional and engineering costs increased at a CAGR of 6.2 percent and salaries and wages increased at a CAGR of 4.7 percent. The Airport's contribution of its allocable share of City pension expenses, described in the following section, has contributed to increasing salaries and wages expenses. The expenses shown in Table 5-1 reflect only expenses due and payable in each year (the cash contribution, reflected in the Airport's rates and charges), and do not reflect certain expenses that are not payable in that year, but recorded pursuant to GASB 68 as reflected in thejEifys^Airport CAFR.

O&M Expenses Re ated to Remaining OMP Airfield Projects
Incremental feffeots^on O&M Expenses from Runway 9C-27C construction and the extension of Runway 9R-27L OMP Airfield/Projects are expected to result from the increased operation and maintenance required to maintain the additional airfield pavement and are estimated to begin in 2021. Projections of these O&M Expenses were developed based on the incremental increase in runway pavement surface area in the Airfield Area with Airfield Area O&M Expenses projected to increase $4.9 million in 2021 and $9.6 million in 2022, the first full year of operation. This projected increase in Airfield Area O&M Expenses is proportionate to the increase in runway square footage, which represents a conservative approach, particularly given that new infrastructure projects do not typically have major maintenance needs immediately after completion.

5.3 Noh-Sigriatory Airline and Non-Airline Revenues

Non-Signatory Airline Revenues are revenues collected from airlines that are not parties'to the Airport Use Agreement or Internatiorial Terminal "Use Agreement. Non-Airline Revenues consist of those Revenues generated at the Airport from sources other than airlines (e.g.; automobile parking, rental cars, restaurants, news and gifts).


Report of the Airport Consultant
CITY OF CHICAGO
CHICAGO OHARE INTERNATIONAL AIRPORT



A majority of the Airport's Non-Airline Revenues are generated from concessions, which includes automobile parking revenues. Table 5-2 presents concession revenues at the Airport from 2011 through 2015. As shown, concession revenues were approximately $211.9 million in 2011, and increased to approximately $244.0 million in 2015, reflecting a CAGR of 3.6 percent during that period. The increase from 2011 through 2015 resulted from the ongoing recovery from the economic recession, as well as continually enhanced concession offerings at the Airport, with local and national favorites well represented. Parking revenues, which represent the Airport's largest Non-Airline Revenue source, were $96.0 million in 2011, and have/increased to $99.2 million in 2015, reflecting a CAGR of 0.8 percent.

Non-Signatory Airline Revenue Projections Non-Signatory Airline Revenues are derived as a function of the signatory rentals, fees, and charges, based on
O&M Expenses, Debt Service, and fund deposits. In the financial analysis in this Report, landing fee revenues
received from non-signatory affiliates of the Airline Parties are considered Non-Signatory Airline Revenues.
Non-Signatory Airline Revenues are budgeted to be approximately $90.7 million in 2016 and are projected to
increase to $140.8 million in 2025, a CAGR of 5.0 percent, which can primarily be attributed to expected
increases in the rates and charges, specifically landing fees, charged to Non-Signatory "Airlines in order to
recover increasing O&M Expenses throughout the Projection Period and debt service-associated with the 2016

The City has a management,agreement with Standard Parking Corporation, a provider of parking facility
management services. Under the agreement, Standard Parking Corporation provides personnel to operate
and maintain the parking facilities at the Airport, provides cashier services^ and provides ground
transportation. The current 5-year contract between the City and Standard Parking commenced January 1,
2013. Standard Parking receives a fixed management fee adjusted annually by a pre,-agreed-upon contract
rate and submits, daily, monthly, and annual accountings to. the CDA. Budgeted parkingVevenues net of City
taxes for 2016 are $101.5 million, or 39.1 percent of concession.revenues. - ¦'<'• . '" '"

Parking revenues at the Airport are a function of on-Airport parking, demandand the availability of parking spaces demanded. Several factors affect on-Airport. parking demand, such S^th^yawet^L^parking products offered (j.e. terminal garage, mid-market surface spaces, and , economy ^sfjaces), off-Airport parking competition; availability of .alternative transportation, such as the Chica'gp Tr^hspprta^pn Authority (CTA) train and taxis, as .well as the impact of transportation network companies (TNCs) spch as Uber and Lyft; and the cost and convenience associated with each of these facilities artci'altematives.

Alternative transportation options include the CTA Blue Line Train providing direct access'to a'station located in the Terminal and connectivity between downtown Chicago and other CTA train lines. According to the CTA, ridership on the Blue Line has been increasing steadily over the past 15 years and has reached record levels, with the highest transit.ridership of any U.S. Airport. . Despite this growth, Airport:parking revenues have also grown over'this period. The City cbntinuesto evaluate the feasibility of a third-party operated express airport train service,:which could provide direct non-stop service between the Airport and downtown Chicago. This express service, if constructed, may impact parking demand at the Airport, but that impact is unknown.

Taxis provide service to and from the Airport, with each departure trip requiring a tax stamp from which the Metropolitan Pier and Exposition Authority (MPEA) receives a fixed fee. Taxi service, as a well-established alternative, factors into the current level of on-Airport parking demand, and with limited ability to develop new products or facilities, is not expected to result in any material incremental long-term effect on on-Airport parking revenues. However, TNCs offer a relatively new and increasingly popular transportation alternative that may impact on-Airport parking revenues. On November 24, 2015, TNCs secured permission from the City to offer TNC service at the Airport, and while TNCs may have been servicing the Airport'before that time without permission, given the recent emergence of TNCs, there is not sufficient data a'vailable^to meaningfully assess the degree to which they are capturing demand share at the expense ojf.,on.;Airport^p^k^ng or other forms of ground transportation such as taxis and mass transit options. The^inrpa^Jof TNCs to on-Airport parking revenues will be clearer as the industry matures and tracking of TNCAs Airport passengers are forecast to increase over the Projection^1m6c^ in Chapter 4 of this
Report, it is assumed that on-Airport parking demand will also increase at a rate consistent with the increase in enplaned passengers. Increased on-Airport parking demand \p.^er the Projection Period could create parking capacity issues at the Airport. To accommodate futo1^''d^man'd^^'City is currently constructing the Multimodal Facility which will include approximately 2,000(parkiny spaces with direct access to the ATS, and has planned a new parking garage as part of the Airport's capital program. The Multimodal Facility, expected to be completed at the end of 2018, will accommodate demar^for mid-market parking. The planned parking garage construction will provide customers ty^cajlyj^parki no, in the Terminal Garage another option to optimize their level of convenience. Additional irif^rrnatipn^regarding these capital projects is included in Chapter 2 of this Report.
An increase in parking rates at the Airpdr^requires^ap'proval by the:City Council, and while currently there are no proposed rate increases uncle^City Co^ncikreview, CDA may elect to seek approval from City Council for parking rate increases on existing_facilities and to set parking rates on new facilities opened during the Projection Period. Parking rate^ncreases would likely result in increases in parking revenues to the Airport. The last parking rate increase was jmplemented on January 1, 2012.

International Terminal Concessions
Effective September 1, 2011, the CDA executed a 20-year concession agreement with Westfield Group to enhance the concessions in the'''international' Terminal. Under the Iriternational Terminal concession agreement, Westfield completed'a $26'million renovation that included the addition of 24 new dining and retail outlets, including 11 local Chicago brands; a redesigned TSA checkpoint; a new dining lounge and new bathrooms; and new seating, lighting, signage, arid fixtures throughout the International Terminal.

Under the previous concession agreement for the International Terminal, concession sales were approximately $25.0 million annually. Under the new agreement, concession sales increased 84.8 percent to $46.2 million in 2015. These sales generated approximately $7.2 million in revenue for the Airport, more.than double the revenue in 2010, the last year prior to the start of the redevelopment.

PASSENGER, FACILITY CHARGE REVENUE
The City has^FAAvapprbval to impose a PFC at the Airport and to use PFC Revenue for approved Airport projects, indu'dingJDMP Airfield Projects.

PFC Program Highlights
« The City collects a $4.50 PFC per eligible enplaned passenger less an $0.11 airline processing charge. No increase in the PFC collection level was assumed in the projections. No decrease in the PFC collection level is required based on current PFC approvals.
The City has approved authority from the FAA to impose a PFC and use PFC Revenues for all project costs anticipated to be funded with PFC Revenues for OMP Phase 1, OMP Phase 2A, and the remaining OMP Airfield Projects.

As of September 2016, the City has received authority to impose a PFC and use $6.55 billion of PFC Revenues at the Airport and an estimated charge expiration date of February 1, 2039. As of June 2016, PFC Revenues received by the City for use at the Airport, including investment earnings, totaled approximately $2.75 billion.
In 2015, PFC Revenues totaled approximately $143.3 million, reflecting PFCs paid by approximately 84.5 percent of enplanements at the Airport. /'/
The estimated balance in the City's PFC Revenue funds.as of January l, 2016 was'$179.0 million.

The Net Signatory Airline Requirement constitutes.the total amount that must be paid.-by'the Airline Parties
and the International Terminal Airline Parties under the Airport Use Agreement and th^iternational Terminal
Use Agreement, respectively, through Landing Fees, Terminal Area Rentals, Terminal Area^Use Charges,
International Terminal Enplaned and Deplaned Common Use Charges, and Fi^lTng\System Fee's during the

5.7 Calculation of Airline Parties' Airport Fees and Charges

Under the Airport Use Agreement and the International Terminal Use Agreement, the Airfield Area, the
Terminal Area, the International Terminal Area, and the Fueling System each generate rentals, fees, or charges
payable by the airlines that are signatory to such agreements. The Airport Fees and Charges>presented in this
section for 2016 through 2018 reflect the rate-setting methodology in the Airport Use-Agreement and the
International Terminal Use Agreement. In the financial projections presented hereirij'a continuation of the
current Airport residual rate-setting methodology was assumed through 2025;-see Sectiori\5.1.1 of this
Chapter. /^^)) ^
Applicable Non-Airline Revenues (i.e., rentals, concession revenues, and^rei'mbursements), as well as the following costs, are allocated to each CRC to calculate applicable ra.tes'used^tp generate such fees, rentals, and charges:
O&M Expenses. Includes the O&M Expenses (direcfand^allocated indirect) attributable to the CRC.
Net Debt Service. Includes the portion of debrseryiceynet of capitalized interest, and debt service

5.7.1 AIRFIELD AREA x£^>
Generally, Landing Fees are calculatea>by first determining the net cost of the Airfield Area, which consists of portions of the following: sutrV'of O&jyl Expenses, Net Debt Sen/ice, fund deposit requirements, and the net deficit of the InternationaJ^rminaJrAfie'a less the sum of projected Non-Airline Revenues and net revenues of the InternationjiJJerminal^Area The Net Cost of the Airfield Area is allocated among Signatory, and Non-Signatory AirlineTbn"trie basisNsf the approved maximum landed weight of all aircraft. Each Signatory Airline and Non-Signatory Airiihe pays Landing Fees on the basis of the ratio of its total approved maximum landed weight-^tb^-he tb.talva£prbved maximum landed weight of all Signatory Airlines and Non-Signatory Airlines.
The landed weight oHiircraft landed by certain classes on Non-Signatory Airlines may be increased by Non-v I' l ^
Signatory Air^ne^remium factors to be determined by the City's Commissioner of Aviation from time to time.
In order to avoid "private business use" of the Airfield Area under federal tax law, certain modifications to the rate-setting methodology described in the preceding paragraph have been in effect since November 2005. The purpose, and effect of these modifications are to cause the Airline Fees and Charges paid by the Airline Parties relating to their use of the Airfield Area to be computed without regard to deficits or surpluses relating to the use of the Airfield Area by entities other than the Airline Parties.

5.8 Reasonableness of Airport User Fees

Table B-9 in ArJpendixNB^at the end of this Report presents the airline revenue resulting from the previously describjed^?^.tals/>fe^s^nd charges. Consistent with the Airport Use Agreement and International Terminal Use A^reemjeht, the^total Signatory Airline revenue presented in Table B-9 equals the Net Signatory Airline Requirement prps'ented in Table B-7.
3.1 AIRLINE COST
A general test of the reasonableness of airport user fees is to compare projected airline costs in a manner that accounts for airline activity. One approach is to measure airport user fees on a per enplanement (CPE) basis. By comparing this metric on a year-over-year basis and by comparing it to airlines' revenue and estimated costs allocated to the Airport, the reasonableness of Airport user fees can be determined. The airline CPE is calculated by dividing the Total Airline Requirement by the number of enplaned passengers at the Airport.

Exhibit 5-13 shows the projected airline CPE at the Airport As shown, the CPE is projected to increase from $17.49 in 2016 to $25.46 in 2025, which equates to $19.51 in 2016 dollars assuming 3 percent inflation. Notable increases include the following:
2017 through 2025 - Incremental increases in CPE associated with City pension contributions.

The projected'Airport user fees shown in Exhibit 5-13 are evaluated in this analysis.to be reasonable based on the expectation that these fees will not deter forecasted demand for ai.r traffic at the Airport as airlines continue to deploy capacity to'airport's based on available resources. The projected Airport user fees in this analysis are deemed to be reasonable based on the following combination of factors:

Large population and strong economic base - The Airport is located in the third-most populous metropolitan region in the 'United'States and'is ranked fourth in the nation in terms of domestic O&D passengers in calendar year 2015 - following the New York, Los Angeles, and San Francisco markets. The Airport's Air Trade Area has a large, diverse economic base that supports business and leisure

travel. Projected economic variables indicate that the Air Trade Area will remain a destination that attracts both business and tourist visitors, positively affecting the demand for future inbound airline travel. Projected Air Trade Area economic variables further support the continued growth of local outbound passengers.
Attractive geographical location - The Airport's central location and proximity to heavily traveled east-west airways make it a natural location for airline hub activities and is complementary to airline route networks.
Important hub for United and American - The Airport is a major connecting hub^fpr United and American within their United States domestic route networks, andJ^is'lTn 'importantsinternational gateway-for European, Asian and Canadian passenger traffic, providing strong-corjnectivity to flights

of international alliance partners. As estimated in Section 4.1 of_this Re^o^t, the Airport is the second
highest contributor to profit for United and the fourth highes^eb'irt^ri^^Ktoprofit for American. The
Airport is also an increasingly important airport within the;|route networks^of several United States
low-cost carriers. Generally, Airport user fees are not aJcey^contributor,to airline's profitability in the
United States. \ xx^-- ^
Increases in debt are associated with capital prpjectS'that allow for growth - Airport user fees during the Projection Period are calculatel recover debt service and operating costs partially attributable to significant capital projec^^jthouglxrrfhe funding of these projects is anticipated to result in increased Airport user fees^fhese pro^cts^ifpport projected long-term growth at the Airport.
In summary, Airport user fees, although^io\r?easiffgd6verrthe Projection Period, are one of many factors that are considered by airlines when evaluating air^ervice. Airport user fees were approximately 6.7 percent of system-wide total airline operatn^g costs according to the airline industry group Airlines for America" and are one of many factors airlinei;-consic^r^when allocating capacity resources.

The Bonds have been authorized by the City for the primary purpose of refunding bonds previously issued for the purpose of providing funds to finance the cost of certain capital projects at Chicago O'Hare International Airport (the "Airport").

The Bonds are being issued pursuant to a Master Indenture of Trust Securing Chicago O'Hare International Airport General Airport Revenue Senior Lien Obligations, dated as of September 1, 2012 (the "Indenture"), between the City and U.S. Bank National Association, as Trustee (the "Trustee"), and a Fifty-Ninth Supplemental Indenture Securing Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2017A, dated as of June 1, 2017 (the1 "Fifty-Ninth Supplemental Indenture"), between the City and the Trustee.

F-2

Based upon the foregoing we are of the opinion that:
The City is a municipal corporation duly existing under the laws of the State of Illinois and is a home rule unit of local government within the meaning of Section 6(a) of Article VII of the 1970 Illinois Constitution. The City has all requisite power and authority under the Constitution and the laws of the State of Illinois and the Bond Ordinance (i) to enter into the Indenture and the Fifty-Ninth Supplemental Indenture with the Trustee and to issue the Bonds thereunder, and (ii) to improve, maintain and operate the Airport and to charge and collect rents, fees and other charges for the use and services of the Airport and to perform all of its obligations under the Indenture and the Fifty-Ninth Supplemental Indenture in those respects.
The Bond Ordinance is in full force and effect and is valid and binding upon the City in accordance with its terms. The Indenture and the Fifty-Ninth Supplemental Indenture have been duly and lawfully authorized, executed and delivered by the City, are in full force and effect, and constitute valid and binding obligations of the City legally enforceable in accordance with their terms, except as enforceability may be limited by laws relating to bankruptcy, insolvency,.moratorium, reorganization and other similar laws- affecting creditors' rights .generally and by equitable principles, whether considered at law or in equity, including the exercise of judicial discretion.
The Bonds have been duly authorized and issued, are the legal, valid and binding limited obligations of the City, are entitled to the benefits and security of the Indenture and the Fifty-Ninth Supplemental Indenture, and are enforceable in accordance with their terms .and the terms of the Fifty-Ninth Supplemental Indenture, except that the rights of the owners of the Bonds and the enforceability of the Bonds may be limited by bankruptcy,' insolvency, moratorium, reorganization and other similar laws affecting creditors' rights andi by equitable principles, whether considered at law or in equity, including the exercise of judicial discretion.
The Bonds are payable solely from the Revenues deposited in the 2017A Dedicated Sub-Fund maintained by the Trustee under the Fifty-Ninth Supplemental Indenture, the Common Debt Service Reserve Sub-Fund on a parity with other Common Reserve Bonds and certain other amounts as provided in the Indenture and the Fifty-Ninth Supplemental Indenture. The Bonds and the interest thereon are limited obligations of the City and do not constitute an indebtedness of the City within the meaning of any state constitutional or statutory limitation or give rise to a charge against its general credit or taxing powers. Neither the faith and credit nor the taxing power of the State of Illinois, the City or any political subdivision of the State of Illinois is pledged to the payment of the principal of, premium, if any, or interest on the Bonds.
The Indenture and the Fifty-Ninth Supplemental Indenture create the valid and binding assignments and pledges which they purport to create of the amounts assigned and pledged to the Trustee under the Indenture and the Fifty-Ninth Supplemental Indenture.

6. Subject to the City's compliance with certain covenants, under present law, interest on the Bonds is excludable from gross income of the owners thereof for federal income tax purposes and is not included as ah item of tax preference in computing the alternative minimum tax for individuals and corporations under the Internal Revenue Code of 1986, as amended, but we express no opinion as to whether interest on the Bonds is taken into account in computing adjusted current earnings, which is used in determining the federal alternative minimum tax for certain corporations. Failure to comply with certain of such City covenants could cause interest on the Bonds to be includible in .gross income for federal income tax-purposes retroactively to the date of issuance; of the Bonds. Ownership of the Bonds may result in .other federal tax consequences to. certain taxpayers, and. .we express no .opinion regarding any such collateral consequences arising with respect to the Bonds. In rendering our opinion on • tax exemption1,-we have relied on the mathematical tdomputation of the yield on the Bonds and the yield on certain investments by Robert Thomas, CPA L'LC, Certified Public • !. Accountants.

The Bonds have been authorized by the City for the primary purpose of refunding bonds previously issued for the purpose of providing funds to finance the cost of certain capital projects at Chicago O'Hare International Airport (the "Airport").

The Bonds are being issued pursuant to a Master Indenture of Trust Securing Chicago O'Hare International Airport General Airport Revenue Senior Lien Obligations, dated as of September 1, 2012 (the "Indenture"), between the City and U.S. Bank National Association, as Trustee (the "Trustee"), and a Sixty-First Supplemental Indenture Securing Chicago O'Hare International Airport General Airport Senior Lien Revenue Refunding Bonds, Series 2017C, dated as of June 1, 2017 (the "Sixty-First Supplemental Indenture"), between the City and the Trustee. The Bonds are Senior Lien Obligations authorized under the Indenture and are payable solely from and secured by a pledge of Revenues of the Airport and Pledged Other Available Moneys as, and to the extent, provided in the Indenture and the Sixty-First Supplemental Indenture. Terms used herein that are defined in the Indenture and the Sixty-First Supplemental Indenture shall have the meanings set forth therein unless otherwise defined herein.

The Pledged Other Available Moneys are derived from grant funds expected to be received by the City from the Federal Aviation Administration ;(the "Grant Receipts"). The payment of grant funds constituting Grant Receipts is not a contractual obligation of the United States of America and the eligibility of the City to receive grant funds is subject to the City's continuing compliance with applicable Federal laws and regulations and the applicable Grant Letter of Intent. We express no opinion as to the rights or remedies of the City with respect to the Grant Receipts.

Under the terms of the Indenture, the City has previously issued Senior Lien Obligations that are presently outstanding and the City may hereafter authorize and issue additional Senior Lien Obligations as permitted by the Indenture.

In our capacity as bond counsel, we have examined, among other things, the following:
certified copies of the proceedings of the City Council adopting the Bond Ordinance and authorizing, among other things, the execution and delivery of the Sixty-First Supplemental Indenture and the issuance of the Bonds;
certified copy of the Bond Ordinance;
an executed counterpart of the Indenture and the Sixty-First Supplemental Indenture; and
such other certifications, documents, showings and related matters of law as we have deemed necessary in order to render this opinion.

Based upon the foregoing we are of the opinion that:
The City is a municipal corporation duly existing under the laws of the State of Illinois and is a home rule unit of local government within the meaning of Section 6(a) of Article VII of the 1970 Illinois Constitution. The City has all requisite power and authority under the Constitution and the laws of the State of Illinois and the Bond Ordinance (i) to enter into the Indenture and the Sixty-First Supplemental Indenture with the1 Trustee and to issue the Bonds thereunder, and (ii) to improve, maintain and operate the Airport and to charge and collect rents, fees and other charges for the use and services of the Airport and to perform all of its obligations under the Indenture and the Sixty-First Supplemental Indenture in those respects.
The Bond Ordinance is in full force and effect and is valid and binding upon the City in accordance with its terms. The Indenture and the Sixty-First Supplemental Indenture have been duly and lawfully authorized, executed and delivered by the City, are in full force and effect, and constitute valid and binding obligations of the City legally enforceable in accordance with their terms, except as enforceability may be limited by laws relating to bankruptcy, insolvency, moratorium, reorganization and other similar'laws affecting creditors' rights generally and by equitable-principles, whether considered at law or in equity, including the exercise of judicial discretion.
The Bonds have been duly authorized and issued, are the legal, valid and binding limited obligations of the City, are entitled to the benefits and security of the Indenture and the Sixty-First Supplemental Indenture, and are enforceable in accordance with their terms and the terms of the Sixty-First Supplemental Indenture, except that the


F-11
rights of the owners of the Bonds and the enforceability of the Bonds may be limited by bankruptcy, insolvency, moratorium, reorganization and other similar iaws affecting creditors' rights and by equitable principles, whether considered at law or in equity, including the exercise ol judicial discretion.
The Bonds are payable solely from the Revenues deposited m the 2017C Dedicated Sub-Fund and the Pledged Other Available Moneys deposited in the 2017C Grant Receipts Deposit Account, each maintained by the Trustee under the Sixty-First
... Supplemental Indenture; the Common Debt Service Reserve Sub-Fund on a parity with other Common Reserve Bonds and certain other amounts as provided in the Indenture - -and;'the-Sixty-First Supplemental Indenture. The Bonds and the interest thereon are limited obligations of the City and ;do: not'constitute an indebtedness of the City within the meaning of any state-' constitutional :or statutory limitation or give rise to a charge against its general credit or taxing powers. Neither the faith and credit nor the taxing power of the State of Illinois, the'City"or any political subdivision of the State of Illinois is pledged to the payment of the principal of, premium, if any, or interest on the Bonds.
The Indenture and the Sixty-First Supplemental Indenture create the valid and binding assignments and .pledges t which they purport to. create of the amounts assigned'and pledged to the'.Trustee under.me indenture.and the Sixty-First Supplemental Indenture.

6. Subject to the City's compliance with certain covenants, under present
. ; .. law, interest on the^Bonds; is, .excludable jfrom,.gross income of the owners thereof for

DESCRIPTION OF BOOK-ENTRY ONLY SYSTEM

General. The following information has been furnished by DTC for use in this Official Statement and neither the City nor any Underwriter takes any responsibility for its accuracy or completeness. The DTC Omnibus Proxy record date, as such term is used under this subcaption, is not, and has no relation to, the "Record Date" as defined in Appendix A — "Glossary of Terms" and used in this Official Statement.

DTC will act as securities depository for the 2017 Senior Lien Bonds. The 2017 Senior Lien Bonds will be issued as fully-registered securities registered in the name of Cede & Co. (DTC's partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered 2017 Senior Lien Bond certificate.will be issued for each maturity of each Series of the 2017 Senior Lien Bonds, in the aggregate principal amount of such maturity, and will be deposited with DTC.

DTC, the world's largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over. 100 countries) that DTC's participants ("Direct Participants") deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants' accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DfCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through ,or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants"). DTC has a Standard & Poor's rating of AA+. The DTC Rules applicable to its Participants are on file with the. Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com .

Purchases of 2017 Senior Lien Bonds under the DTC system must be made by or through Direct Participants, which will receive a credit for the 2017 Senior Lien Bonds on DTC's records. The ownership interest of each actual purchaser of each 2017 Senior Lien Bond ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchase.

G-l

Beneficial Owners are. however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or indirect. Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the 2017 Senior Lien Bonds arc to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners.

To facilitate subsequent transfers, all 2017 Senior Lien Bonds deposited by Direct
Participants with DTC are registered'in the name of'DTC's partnership nominee,, Cede & Co., or
such other name as may be requested by'an authorized representative of DTC. The deposit of

Redemption proceeds, distributions, and interest payments on the 2017 Senior Lien Bonds will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit Direct Participants' accounts upon DTC's receipt of funds and corresponding detail information from the City or the Trustee, on the payable date in accordance with their respective holdings shown on DTC's records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such Participant and not of DTC, the Trustee or the City, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the City or the Trustee, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

Under such circumstances, in the event that a successor securities depository is not obtained, certificates for the 2017 Senior Lien Bonds are required to be printed and delivered.

The City may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, certificates for the 2017 Senior Lien Bonds will be printed and delivered to DTC.

For every transfer and exchange of the 2017 Senior Lien Bonds, the Trustee and DTC and the Participants may charge the beneficial owner a sum sufficient to cover any tax, fee or other charge that may be imposed in relation thereto.

The City and the Trustee shall have no responsibility or obligation with respect to (i) the accuracy of the records of DTC, Cede & Co. or any Participant with respect to any ownership interest in the 2017 Senior Lien Bonds, (ii) the delivery to any Participant or any other person, other than an owner, of any notice with respect to the 2017 Senior Lien Bonds, including any notice of redemption, or (iii) the payment to any Participant or any other person, other than an owner, of any amount with respect to principal of or interest on the 2017 Senior Lien Bonds.
